Carbonyl allenylations and propargylations by 3-chloro-1-propyne or 2-propynyl mesylates with tin(IV) chloride and tetrabutylammonium iodide

By the use of tin(IV) chloride and tetrabutylammonium iodide in dichloromethane, 3-chloro-1-propyne or 2-propynyl mesylate can be applied to allenylation and propargylation of aldehydes (carbonyl allenylation and propargylation) to produce a mixture of 1-

Preparation of Polyfunctional Allenic Alcohols by the Regioselective Addition of Functionalized Propargylic Chromium(III) Organometallics to Carbonyl Compounds

The reaction of propargylic halides 1 (X = Cl, Br) with an aldehyde or ketone (0.67 equiv) in the presence of CrCl2 (2.0 equiv) and LiI (2 equiv, necessary if X = Cl) affords allenic alcohols 3 with excellent regioselectivities (3-6percent of the regioiso
