A highly regio- and stereoselective intramolecular [1,5]-hydrogen-transfer process is described. Treatment of gamma-benzyl-protected Co2(CO)6-alpha,gamma-acetylenic diols with BF3 x OEt2 provides bis-homopropargylic alcohols. The reaction occurs within seconds, tolerates a wide range of functionalities, and provides good yields. When the ether

The use of the terphenyl substituent -C(6)H(3)-2,6-Mes(2) (abbreviated Ar) has permitted the synthesis of several new low-coordinate beryllium compounds. Reaction of 1 equiv of LiAr with BeCl(2)(OEt(2))(2) or BeBr(2)(OEt(2))(2) (1) gives the monomeric complexes ArBeX(OEt(2)) (X = Cl (2); Br
