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

New experimental data for production of (7)Be and (22,24)Na in deuteron irradiation of (nat)Mg and Al up to 50 MeV are presented. The induced activity, measured with HPGe spectroscopy, allows us to determine excitation functions of (nat)Mg(d,x) and (27)Al(d,x) reactions
