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

We developed Ni- and Be-free Zr(45+x)Cu(40-x)Al₇Pd₅Nb₃ bulk metallic glasses with large glass-forming ability and unusual plasticity. The alloys have large critical diameters (larger than 10 mm) in a wide composition range (x=0-20). The Zr₅₀Cu₃₅Al₇Pd₅Nb₃ and Zr₅₅Cu₃₀Al₇Pd₅Nb₃ alloys exhibit the largest
