Abstract
[GRAPHICS] Novel Pd-catalyzed sulfinylzincation of activated alkynes was developed, wh erein 1-alkynyl sulfoxides work as a sulfinylating agent. Transfer of the s ulfinyl group proceeded in a highly syn-selective fashion, giving a beta -s ulfinyl vinylzinc species. Using 3,3-dimethyl-1-butynyl p-tolyl sulfoxide a s a sulfinyl source, heterocoupling with propiolate derivatives was also ac complished.
