Equimolar reactions of \(\overline{OGOSb}OPr^i \) with ArOH (substituted phenols) in benzene after usual work-up afford hydrocarbon soluble, monomeric derivatives of the type \(\overline{OGOSbO}Ar\), where G = CHMeCH₂CMe₂ : Ar = C₆H₃Me₂ -2,6 (1), C₆H₃Prⁱ -2-Me-5 (2), C₆H₃Prⁱ -2,6 (3) and G = CMe₂CH₂CH₂CMe₂ : Ar = C₆H₃Me₂ -2,6 (4), C₆H₃Prⁱ ₂ -2,6 (5). The derivative (1) has also been prepared by in situ by equimolar reaction of Sb(OPrⁱ )₃ , HOCHMeCH₂CMe₂OH and HOC₆H₃Me₂ -2,6 in refluxing benzene. All of these new derivatives have been characterized by elemental analyses, molecular weight measurements and spectroscopic (IR and 1H NMR) studies.
