Therefore, a series of five- to ten-membered heterocycles bearing an O-P(S)-O or an O-P(S)-S-S-P(S)-O linkage were synthesized. The synthesis features a novel application of the multicomponent reaction, providing an efficient and environmentally benign method for the preparation of the unusual phosphorus-sulfur heterocycles. Seven representative X-ray structures confirm the formation of these heterocycles.<\/jats:p>","DOI":"10.3390\/molecules22101687","type":"journal-article","created":{"date-parts":[[2017,10,10]],"date-time":"2017-10-10T10:34:29Z","timestamp":1507631669000},"page":"1687","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":3,"title":["Phosphorus-Sulfur Heterocycles Incorporating an O-P(S)-O or O-P(S)-S-S-P(S)-O Scaffold: One-Pot Synthesis and Crystal Structure Study"],"prefix":"10.3390","volume":"22","author":[{"given":"Guoxiong","family":"Hua","sequence":"first","affiliation":[{"name":"EaStCHEM School of Chemistry, University of St Andrews, Fife KY16 9ST, UK"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Kate","family":"Davidson","sequence":"additional","affiliation":[{"name":"EaStCHEM School of Chemistry, University of St Andrews, Fife KY16 9ST, UK"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"David","family":"Cordes","sequence":"additional","affiliation":[{"name":"EaStCHEM School of Chemistry, University of St Andrews, Fife KY16 9ST, UK"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Junyi","family":"Du","sequence":"additional","affiliation":[{"name":"EaStCHEM School of Chemistry, University of St Andrews, Fife KY16 9ST, UK"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9527-6418","authenticated-orcid":false,"given":"Alexandra","family":"Slawin","sequence":"additional","affiliation":[{"name":"EaStCHEM School of Chemistry, University of St Andrews, Fife KY16 9ST, UK"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"J.","family":"Woollins","sequence":"additional","affiliation":[{"name":"EaStCHEM School of Chemistry, University of St Andrews, Fife KY16 9ST, UK"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2017,10,10]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"9655","DOI":"10.1016\/j.tet.2003.09.080","article-title":"N-Trifluoroacetyl arenesulfenamides, effective precursors for synthesis of unsymmetrical disulfides and sulfenamides","volume":"59","author":"Bao","year":"2003","journal-title":"Tetrahedron"},{"key":"ref_2","unstructured":"Cremlyn, R., and An, J.
