Abstract

Abstract A selective reaction of cyclohexanone oxime-blocked tolylene-2, 4-diisocyanate (2, 4-TDI) with amino siloxane was observed, in which amines were capable of discriminating two reactive groups in the 2, 4-TDI molecule. Thus, tolylene-2-tert-butyldimethylsilyloxyethyl carbamide-4-cyclohexanone oxime carbamate was synthesized and its precise structure was determined by single-crystal X-ray diffraction. Moreover, it was found that oxime- ...
