The mass spectral rearrangements of 1,6-bis(arylsulfenyl)-2,4-hexadiynes and 1,6-bis(arylsulfonyl)-2,4-hexadiynes
摘要:
AbstractThe mass spectral. behavior of 1,6‐bis(arylsulfenyl)‐2,4‐hexadiynes and 1,6‐bis(arylsulfonyl)‐2,4‐hexadiynes were examined. The sulfenyl derivatives extruded the hexadiynyl moiety with the formation of ArSSAr fragments. The sulfonyl derivatives, on the other hand, showed no extrusion of the hexadiyne fragment but an expulsion of SO2 and even two SO2 units.

The hexa-2,4-diene derivative (2), obtained from 1,6-di(phenylsulphonyl)hexa-2,4-diyne (1), is shown to undergo simultaneous Isomerization at both double bonds, through an elimination-addition pathway.

Propargylic sulfones can be cis-hydrogenated using commercial zinc powder and ammonium chloride in THF-water at room temperature, the major products being the corresponding (Z)-allylic sulfones. Other reducible groups (alkene, benzyloxy) are not affected. Allenylsulfones are implicated in one of the possible reaction pathways. (c) 2007 Elsevier Ltd. All rights reserved.
