PALLADIUM-CATALYZED REACTION OF 1-AZA-5-GERMA-5-ORGANOBICYCLO[3.3.3]UNDECANE WITH ARYL BROMIDE

Successive treatment of triallylamine with zirconocene chloride hydrid e and germanium tetrachloride affords 1-aza-5-germa-5-chlorobicyclo[3. 3.3]undecane, which is converted to the 5-organo derivatives by the re action with Grignard or lithium reagents. The organo groups showed hig her reactivities toward Stille-type coupling than the corresponding or ganotributylgermanes.
