title: Palladium-catalyzed sulfinylzincation: 1-alkynyl sulfoxides as a sulfinyl anion equivalent.
abstract: [reaction--see text] Novel Pd-catalyzed sulfinylzincation of activated alkynes was developed, wherein 1-alkynyl sulfoxides work as a sulfinylating agent. Transfer of the sulfinyl group proceeded in a highly syn-selective fashion, giving a beta-sulfinyl vinylzinc species. Using 3,3-dimethyl-1-butynyl p-tolyl sulfoxide as a sulfinyl source, heterocoupling with propiolate derivatives was also accomplished.
