METHOD OF PRODUCTION OF TRIS(HALOGENALKYL)PHOSPHATE COMPLEXES WITH Sn, Ti OR Si CHLORIDES Russian patent published in 2008 - IPC C07F9/09 C07F7/02 C07F7/12 C07F7/22 C07F7/28

Abstract RU 2324697 C1

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.
