Uk. Nadir et al., REACTION OF ALPHA-HALOSILANES WITH N-ARYLIDENEARYLSULFONAMIDES - ATTEMPTED SYNTHESIS OF N-ARYLSULFONYLAZIRIDINES, Indian journal of chemistry. Sect. B: organic chemistry, including medical chemistry, 36(2), 1997, pp. 180-181
Reaction of alpha-halosilanes with fluoride ions generates carbanions
I, through the attack of fluoride ion on the Si atom, and these are re
ported to transfer methylene to suitable double bonds(1-3). Thus Kessa
r et al.(4) have shown that II reacts with aldehydes to give oxiranes
and with alpha,beta-unsaturared ketones and esters to yield the corres
ponding cyclopropanes (Scheme I).
