New phosphonous acid aryl ester amide

摘要

Phosphonous acid aryl ester amides of formula (I) and phosphonous acid aryl ester amide halides of formula (II). In the formulae, R1 is Ph with 1-3 substits., benzyl, alpha-methylbenzyl or alpha,alpha-dimethylbenzyl (opt. with 1-3 substits. on the ring) or naphthyl (opt. with 1-5 substits.), where at least 1 substit. is 1-8C alkoxy or alkylthio, 6-10C aryl or aryloxy or halogen with atomic no. 9-35 and the other substits. (exclusively with naphthyl) are 1-8C non-aromatic hydrocarbon gps., or R1 is phenylene (opt. substd. by 1-2 non-aromatic hydrocarbon gps. with 1-8C), naphthylene or biphenylene (opt. substd. with 1-4 non-aromatic hydrocarbon gps. with 1-8C), R2 is 1-18C non-aromatic hydrocarbon gp., or aryl or (substd.) arylmethyl, where the aryl is 6-10C, R3 is H or 1-18C alkoxy or alkylthio or a gp. defined under R2, R4, R5 are 1-22C alkyl, 2-21C oxaalkyl or thiaalkyl, 3-18C alkenyl or alkynyl, 3-24C alkoxycarbonylalkyl, 5-12C cycloalkyl, 6-14C aryl, 7-15C arylalkyl or (substd.) 5-17C piperidin-4-yl or R4, R5 and N form a 5-7 member ring, opt. contg. O, N or S linked through C, n is 1 or 2.
