The proposed compounds are odorless, easy to obtain, and highly effective in removing metal residues, sometimes bringing the metal content below 0.0015\u2005ppm. The most successful of the tested compounds, <jats:bold>II<\/jats:bold>, performs very well, even with challenging polar products. The performance of these scavengers is compared and contrasted with other known techniques, such as silica gel filtration and the use of self\u2010scavenging catalysts. As a result, a new hybrid purification method is devised, which gives better results than using either a self\u2010scavenging catalyst or a scavenger alone. Additionally, isocyanide <jats:bold>II<\/jats:bold> is shown to be a deactivating (reaction quenching) agent for olefin metathesis and superior to ethyl vinyl ether.<\/jats:p>","DOI":"10.1002\/cssc.201500784","type":"journal-article","created":{"date-parts":[[2015,11,11]],"date-time":"2015-11-11T07:27:01Z","timestamp":1447226821000},"page":"4139-4148","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":45,"title":["High\u2010Performance Isocyanide Scavengers for Use in Low\u2010Waste Purification of Olefin Metathesis Products"],"prefix":"10.1002","volume":"8","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-0355-9542","authenticated-orcid":false,"given":"Grzegorz","family":"Szczepaniak","sequence":"first","affiliation":[{"name":"Biological and Chemical Research Centre Faculty of Chemistry University of Warsaw  \u017bwirki i Wigury 101 02-089 Warsaw Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1807-5364","authenticated-orcid":false,"given":"Katarzyna","family":"Urbaniak","sequence":"additional","affiliation":[{"name":"Apeiron Synthesis  Du\u0144ska 9 54-427 Wroc\u0142aw Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-3741-9617","authenticated-orcid":false,"given":"Celina","family":"Wierzbicka","sequence":"additional","affiliation":[{"name":"Apeiron Synthesis  Du\u0144ska 9 54-427 Wroc\u0142aw Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-3312-1602","authenticated-orcid":false,"given":"Krzysztof","family":"Kosi\u0144ski","sequence":"additional","affiliation":[{"name":"Biological and Chemical Research Centre Faculty of Chemistry University of Warsaw  \u017bwirki i Wigury 101 02-089 Warsaw Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7126-7595","authenticated-orcid":false,"given":"Krzysztof","family":"Skowerski","sequence":"additional","affiliation":[{"name":"Apeiron Synthesis  Du\u0144ska 9 54-427 Wroc\u0142aw Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9193-3305","authenticated-orcid":false,"given":"Karol","family":"Grela","sequence":"additional","affiliation":[{"name":"Biological and Chemical Research Centre Faculty of Chemistry University of Warsaw  \u017bwirki i Wigury 101 02-089 Warsaw Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2015,11,11]]},"reference":[{"key":"e_1_2_6_1_1","doi-asserted-by":"publisher","DOI":"10.1021\/cr100346g"},{"key":"e_1_2_6_2_1","doi-asserted-by":"publisher","DOI":"10.1002\/adsc.201100488"},{"key":"e_1_2_6_3_1","doi-asserted-by":"publisher","DOI":"10.1002\/adsc.200900587"},{"key":"e_1_2_6_4_1","doi-asserted-by":"publisher","DOI":"10.1021\/op0255682"},{"key":"e_1_2_6_5_1","doi-asserted-by":"publisher","DOI":"10.1021\/op034072x"},{"key":"e_1_2_6_6_1","doi-asserted-by":"publisher","DOI":"10.1021\/op700288p"},{"key":"e_1_2_6_7_1","doi-asserted-by":"publisher","DOI":"10.1021\/op600280g"},{"key":"e_1_2_6_8_1","doi-asserted-by":"publisher","DOI":"10.1021\/op800225f"},{"key":"e_1_2_6_9_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.tet.2009.06.022"},{"key":"e_1_2_6_10_1","doi-asserted-by":"publisher","DOI":"10.1021\/op300296t"},{"key":"e_1_2_6_11_1","unstructured":"European Medicines Agency Specification limits for residues of metal catalysts CHMP\/SWP\/4446\/2000 2008."},{"key":"e_1_2_6_12_1","doi-asserted-by":"publisher","DOI":"10.1021\/ja952676d"},{"key":"e_1_2_6_13_1","doi-asserted-by":"publisher","DOI":"10.1021\/ol990909q"},{"key":"e_1_2_6_14_1","doi-asserted-by":"publisher","DOI":"10.1021\/ja001179g"},{"key":"e_1_2_6_15_1","doi-asserted-by":"publisher","DOI":"10.1002\/1521-3773(20021104)41:21<4038::AID-ANIE4038>3.0.CO;2-0"},{"key":"e_1_2_6_15_2","doi-asserted-by":"publisher","DOI":"10.1002\/1521-3757(20021104)114:21<4210::AID-ANGE4210>3.0.CO;2-J"},{"key":"e_1_2_6_16_1","doi-asserted-by":"publisher","DOI":"10.1039\/a900187e"},{"key":"e_1_2_6_17_1","doi-asserted-by":"publisher","DOI":"10.1002\/ejic.200700879"},{"key":"e_1_2_6_18_1","doi-asserted-by":"publisher","DOI":"10.1002\/9781118711613.ch3"},{"key":"e_1_2_6_19_1","doi-asserted-by":"publisher","DOI":"10.1002\/anie.200500369"},{"key":"e_1_2_6_19_2","doi-asserted-by":"publisher","DOI":"10.1002\/ange.200500369"},{"key":"e_1_2_6_20_1","first-page":"22","volume":"32","author":"Olszewski T.","year":"2014","journal-title":"Chim.
