1,2-propadienyltributylstannane

The reaction of 1,2-propadienyltributylstannane with aldehydes in the presence of TiCl4 at -78°C gives homo-propargylic alcohols in high yields (Scheme 1) (1).

1,2-propadienyltributylstannane

A route to the synthesis of chiral propadienyl-carbinols has been described by Corey (Scheme 2) (2).

1,2-propadienyltributylstannane
