for the synthesis of homopropargylic alcohols usingpropargyliccarbonates as pronucleophiles is reported. The reaction is based on a combination of transition metal (palladium) and radical chemistry (titanium). The reaction takes place with an excellent regioselectivity and tolerates a great degree of substitution of the starting propargyliccarbonate, thus being an interesting tool in the context
