✦ Synopsis


A new algorithm for computing the homology module of e finitely generated chain complex la given. It la based on local one-step reductions of the size of the initial chain complex and it hae a clear geometrical interpretation. The complexity of the algorithm ls dllueeed in special CliSB.

This work reports the catalytic activity of the oxo-complexes HReO 4 , MoO 2 (acac) 2 , WO 2 Cl 2 , and VO(acac) 2 in the reduction of sulfoxides with PhSiH 3 or HBcat. The results obtained showed that the catalyst systems PhSiH 3 /HReO 4 (5 mol %) and HBcat/HReO 4 (5 mol %) are highly efficient for
