Reactions of tri-p-tolylantimony with carboxylic and arylsulfonic acids and phenols
摘要:
The tri-p-tolylantimony dicarboxylates were synthesized by the reaction of tri-p-tolylantimony with trifluoroacetic, trichloroacetic, and iodoacetic acids in the absence of oxygen. The amount of the corresponding compound in the reaction product is defined by the nature of the reacting acid. The reaction of tri-p-tolylantimony with toluenesulfonic acid and 2,4,6-trinitrophenol under similar conditions leads to the formation of tri-p-tolylantimony bis(toluenesulfonate) and bis(2,4,6-trinitrophenoxide) respectively with the yield reaching 82%. According to X-ray diffraction data, in the two crystallographically independent molecules of tri-p-tolylantimony bis(trifluoroacetate) the Sb atoms have distorted trigonal-bipyramidal coordination.
