M. Journet et al., HIGHLY EFFICIENT SYNTHESIS OF ALPHA,BETA-ACETYLENIC ALDEHYDES FROM TERMINAL ALKYNES USING DMF AS THE FORMYLATING REAGENT, Tetrahedron letters, 39(36), 1998, pp. 6427-6428
The formylation of lithium acetylides with DMF led to alpha,beta-acety
lenic aldehydes in excellent yields (>94%). A reverse quench into a ph
osphate buffer (10% aqueous KH2PO4 ,4 equiv) proved ro he the key for
this high-yielding reaction. (C) 1998 Elsevier Science Ltd. All rights
