Carboxylic acid 1-alkene-4-yl and 1-alkyne-4-yl, esters (RCH(CH2CHCH2)OCOR′ ad RCH(CH2CCH)OCOR′, R = R′ or R ≠ R′ = alkyl or alkenyl group) can be readily prepared in high yields by transalkoxylation reactions between 4-n-dibutylchlorostannoxy-1-alkenes or 4-n-dibutylchlorostannoxy-1-alkynes with acyl chlorides. This represents a general route for preparation of esters containing allyl or propargyl groups.

Abstract
Carboxylic acid 1-alkene-4-yl and 1-alkyne-4-yl, esters (RCH(CH2CHCH2)OCOR′ ad RCH(CH2CCH)OCOR′, R = R′ or R ≠ R′ = alkyl or alkenyl group) can be readily prepared in high yields by transalkoxylation reactions between 4-n-dibutylchlorostannoxy-1-alkenes or 4-n-dibutylchlorostannoxy-1-alkynes with acyl chlorides. This represents a general route for preparation of esters containing allyl or propargyl groups.
