摘要

Sf; Reactions between allyl dithiocarbonates (eg com-pound 10, 17 Scheme 4), allyl dithioiminocarbonates, 18 allyl sulfides (eg compound 1119) or allyl sulfones (eg compound 122) and Bu3Sn'radicals also lead to allyl-stannanes. Due to the elevated temperatures, none of these reactions reveals more than a modest trans selectivity; trans/cis ratios vary between 90: 10 and 70: 30.
