Water promoted organic chemistry . The allylation of carbonyl (and acetal) compounds by tetraallylstannane
Abstract
A mild and effective water based procedure for the allylation of acetals, alkanals and alkanones is described. This procedure successfully minimises the environmental impact of tetraallylstannane by allowing isolation of the inorganic stannane salts and recycling of the organic solvents used to extract the homoallylic alcohol products. Yields are good to excellent.
