In this paper we give a complete classification of two-step nilpotent Leibniz algebras in terms Kronecker modules associated with pairs bilinear forms. particular, describe the complex and real case indecomposable Heisenberg as generalization classical $(2n+1)-$dimensional Lie algebra $\mathfrak{h}_{2n+1}$. Then use - local racks correspondence proposed by S. Covez to show that have always glob...

Improvements in the two-step synthesis of 1,1,1,3,3,3-hexafluoro-2- (fluoromehoxy)propane (Sevoflurane) that result in the product cost reduction, safety level enhancement and positive environmental impacts are described. This process consists of chloromethylation reaction of 1,1,1,3,3,3-hexafluoro-2-propanol (HFIP) followed by a halogen-exchange fluorination. This is the first synthesis of Sev...
