Tin/mercury exchange in 1,2-distannyl-1-alkenes and 1-silyl-2-stannyl-1-alkenes
摘要:
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.
