In this work, ring-opening reactions of cyclopropane derivatives under hydrogen catalyzed by metal nanoparticles (NPs) in the liquid phase were studied. 40-atom rhodium (Rh) NPs, encapsulated by dendrimer molecules and supported in mesoporous silica, catalyzed the ring opening of cyclopropylbenzene at room temperature under hydrogen in benzene, and the turnover frequency (TOF) was higher than other metals or the Rh homogeneous catalyst counterparts. Comparison of reactants with various substitution groups showed that electron donation on the three-membered ring boosted the TOF of ring opening. The linear products formed with 100% selectivity for ring opening of all reactants catalyzed by the Rh NP. Surface Rh(0) acted as the active site in the NP. The capping agent played an important role in the ring-opening reaction kinetics. Larger particle size tended to show higher TOF and smaller reaction activation energy for Rh NPs encapsulated in either dendrimer or poly(vinylpyrrolidone). The generation\/size of dendrimer and surface group also affected the reaction rate and activation energy.<\/jats:p>","DOI":"10.1021\/jacs.6b03977","type":"journal-article","created":{"date-parts":[[2016,6,20]],"date-time":"2016-06-20T17:27:41Z","timestamp":1466443661000},"page":"8533-8537","source":"Crossref","is-referenced-by-count":43,"title":["Metal\nNanoparticles Catalyzed Selective Carbon\u2013Carbon\nBond Activation in the Liquid Phase"],"prefix":"10.1021","volume":"138","author":[{"given":"Rong","family":"Ye","sequence":"first","affiliation":[{"name":"University of California , , , ,","place":["Berkeley, California, United States, 94720"]},{"name":"Lawrence Berkeley National Laboratory , , 1 Cyclotron Road , , ,","place":["Berkeley, California, United States, 94720"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Bing","family":"Yuan","sequence":"additional","affiliation":[{"name":"University of California , , , ,","place":["Berkeley, California, United States, 94720"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jie","family":"Zhao","sequence":"additional","affiliation":[{"name":"University of California , , , ,","place":["Berkeley, California, United States, 94720"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Walter T.","family":"Ralston","sequence":"additional","affiliation":[{"name":"University of California , , , ,","place":["Berkeley, California, United States, 94720"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Chung-Yeh","family":"Wu","sequence":"additional","affiliation":[{"name":"University of California , , , ,","place":["Berkeley, California, United States, 94720"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ebru","family":"Unel Barin","sequence":"additional","affiliation":[{"name":"University of California , , , ,","place":["Berkeley, California, United States, 94720"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"F.
