A one-pot procedure for the synthesis of iodoalkynes from aldehydes
Michel, Patrick,Rassat, Andreì?
, p. 8579 - 8581 (1999)
Iodoalkynes R-Ca??CI were obtained in good yield through a one-pot procedure by reaction of the aldehydes RCHO with diiodomethyltriphenylphosphorane first generated in situ from iodoform, triphenylphosphine and t-BuOK.
