Mass spectral rearrangements ofN-(4′-arylthio-2′-butynyl)N-(2″-arylthio-2″-propenyl)-p-toluidines,N,N-bis(2′-arylthio-2′-propenyl)-p-toluidines and 1,2-bis(arylthio)acenaphthenes
摘要:
AbstractUnder electron impact the title compounds display, in addition to the sequential loss of the arylthio groups, the elimination of a bisaryl disulphide moiety, but they do not eliminate sulphur. The behaviour of the p‐toluidine derivatives supports the rearrangement pathway proposed earlier for N,N‐bis(4′‐arylthio‐2′‐butynyl)anilines.

A very simple procedure is described for the efficient synthesis of vinyl sulfides by hydrothiolation of terminal alkynes using 1-n-butyl-3-methylimidazolium methylselenite, [bmim][SeO2(OCH3)]. The reaction proceeds cleanly under mild, base-free conditions and was performed with aromatic and aliphatic thiols. (C) 2012 Elsevier Ltd. All rights reserved.
