Synthesis and antimicrobial activity of novel 3 substituted 1,5-dihydro-2,4,3-benzodioxaphosphepine 3-oxides

Novel 3 substituted 1,5-dihydro-2,4,3-benzodioxaphosphepine 3-oxides (5a-h) were synthesized by reacting 1,2-benzenedimethanol (1) with phosphorus tribromide in the presence of triethylamine at 0-30°C and subsequent reaction of the monobromide (2) with di

Conversion of Phosphinic into Phosphinous Esters through Nickelocene Reduktion-complexation of Phosphinothioic O-Esters. A New Synthesis of Carbon-phosphorus Heterocycles

A new procedure for reducing a phosphinate (LO) into the corresponding phosphinite (L) includes the following steps: LO -> LS -> CpNi(I)L -> NiL4 -> L (Cp = cyclopentadiene); such as scheme is illustrated by the syntheses of 2-phenyl-1,2-oxaphospholane an
