PHENYLETHYNYLTRI-N-BUTYLTIN Chemical Properties,Usage,Production

Uses

Tributyl(phenylethynyl)tin can be used:

• As a substrate in the palladium-catalyzed homocoupling of?organostannanes to yield biaryl compounds.
• To prepare various enynals, which are employed in the synthesis of substituted benzene derivatives catalyzed by nickel.
• In one of the key synthetic steps for the preparation of β-alkynylcorroles.
