Cleavage of Carbon--Sulfur Bonds in the Synthesis of alpha-Haloalkyl Carbonates.
摘要:
alpha-Chloroalkyl and alpha-bromoalkyl carbonates have been prepared by cleavage of alpha-arylthioalkyl carbonates with sulfuryl chloride or bromine, respectively. The alpha-arylthioalkyl carbonates are prepared by reaction of the hemithioacetal 1 with chloroformates or by a destannylative tin-Pummerer rearrangement of alpha-stannyl sulfoxides.

alpha-Thioalkyl esters and carbonates have been prepared by a tin-Pummerer rearrangement in reactions of alpha-stannylated sulfoxides with acid chlorides or chloroformates, respectively. Acid chlorides have a higher reactivity than chloroformates in this reaction.
