Synthesis of Organophosphorus‐Substituted Amides of Carbonic Acids with PCHNC(O) and 2,6‐Di‐tert‐butyl‐4‐methylphenol Fragments

Abstract

Convenient procedures for the synthesis of new organophosphorus-substituted amides of various carbonic acids with PCHNC(O) and 2,6-di-tertbutyl-4-methylphenol (ionol) fragments, starting from the adducts of imines and acyl chlorides, are proposed.Some properties of the new synthesized organophosphorus amides are presented.

Synthesis of mono‐ and bisorganophosphorus substituted amides of unsaturated carboxylic acids with PCHNC(O) and antioxidant fragments

“…Hence, adducts A, which are easily formed from anisal(methyl)amine and crotonoyl, cinnamoyl, sorbinoyl, and oleoyl chlorides in methylene chloride (cf. [9]), react with trimethylsilyl phosphites by the Arbuzov reaction scheme to give the corresponding amides 1-5 with high yields (Eq. (1)).…”

“…In this work, we propose the unique way for the synthesis of new monoand bisorganophosphorus substituted amides of unsaturated carboxylic acids with PCHNC(O) and antioxidant fragments (cf. [9,10]), which was based on available imines and the corresponding acyl chlorides [11], and trimethylsilyl phosphites [12].…”
