ALKOXY-DIRECTED INSERTION OF CARBON-CARBON DOUBLE-BONDS INTO TANTALUM-ALKYNE COMPLEXES - CHEMOSELECTIVE AND STEREOSELECTIVE ADDITION OF ALKENYL GROUPS TO OLEFINS

Chemo- and stereoselective addition of alkenyl groups at terminal posi tions of olefins is accomplished by the reaction between tantalum-alky ne complexes and terminal olefins having adjacent hydroxyl groups.
