Synthesis of 2-R-1,3-dioxanes, derivatives of functionally substituted aldehydes of vanillin series
摘要:
By the condensation of substituted aldehydes of vanillin series with 1,3-propanediol in boiling benzene in the presence of sulfo cation exchanger FIBAN K-1 as catalyst functionally 2-R-substituted 1,3-dioxanes were synthesized.

Previously unknown m-carborane-containing azomethines (Schiff bases) were synthesized by the reaction of esters derived from vanillin or vanillal and m-carboranecarboxylic acid with primary amines in absolute methanol.

1,3- and 1,4-bis[3-methoxy and ethoxy-4-(m-carborane-C-methanoyloxy)phenylmethylene]phenylenediamines were synthesized from the vanillin and vanillal m-carborane-C-carboxylates by the reaction with 1,3- and 1,4-phenylenediamines in anhydrous methanol. Reduction of the title compounds with Na[BH(OAc)(3)] in benzene yielded 1,3- and 1,4-bis[3-methoxy- and ethoxy-4-(m-carborane-C-methanoyloxy)phenylmethyl] phenylenediamines.
