Cyclopropanation and epoxidation of 1,2-distannylalkenes and 1-silyl-2-stannylalkenes
摘要:
Cyclopropanation of the title compounds is possible under certain conditions (CH2I2-Sm (Hg)) in special cases, but epoxidation is apparently a general reaction which occurs readily in a stereospecific manner when they are treated with m-chloroperbenzoic acid.

1,2-Bis(chloromercuri)alkenes, 1-trimethylsilyl-2-chloromercuri-alkenes and 1-trimethylsilyl-2-organomercurialkenes can be readily made by transmetallation of the corresponding trimethyltin compounds with HgCl2 and RHgCl; their structures have been confirmed by multinuclear NMR data. The new compounds are expected to have a large synthetic potential involving lithium/mercury exchange, and subsequent reaction with electrophilic reagents.
