METHOD OF PRODUCTION OF TRIS(HALOGENALKYL)PHOSPHATE COMPLEXES WITH Sn, Ti OR Si CHLORIDES

摘要

FIELD: chemistry.;SUBSTANCE: scope of invention covers production of complexes of Sn or Ti chlorides or of Si phenyltrichloride with common formula 2(RO)₃P=O·ER₁Cl₃, where E = Sn, Ti or Si; R = -CH₂CH₂Cl, -CH₂CH(Cl)CH₃, -CH₂CH(Br)CH₂(Br); R₁₌Cl or -C₆H₅, suitable for use as catalysts in organic synthesis. The method includes interaction of tris(halogenalkyl)phosphates with Sn or Ti tetrachlorides or Si phenyltrichloride at ambient temperature and mole ratio phosphate: chloride 2 : 1.;EFFECT: production of new complexes of chlorides with orto-phosphate acid esters.;5 ex, 2 tbl
