Synthesis of tetra- and triarylantimony fluorobenzoates

摘要

Pentaarylantimonies Ar_5Sb(Ar = Ph, p-Tol) was reacted with triarylantimony bis(perfluorobenzoate) and bis(3,4,5-trifluorobenzoate) in toluene at elevated temperature to obtain tetraarylantimony fluorobenzoates in 90% yield. Triarylantimony bis(fluorobenzoates) were prepared in an yield of up to 98% from triarylstibine and fluorobenzoic acid by oxidative addition in ether in the presence of hydrogen peroxide.
