Sigmatropic isomerizations in 2-aza-allylic systems. Part X. Prototropic and chlorotropic rearrangements in fluoroalkyl- substituted 1,3-dichloro-imines
The photochemical chlorination of N-benzylimidoyl chlorides RC(CI)=NCH2Ph (R=CF3, CFCI2, C3F7, tBu, Ar) results in RC(CI)=NCH(CI)Ph or its mixture with isomeric RCCI2N=CHPh depending on the nature of the substituent R. 1,3-Prototropic and 1,3-chlorotropic rearrangements in the chlorination products have been observed and investigated.
N-苄基亚氨基酰氯RC(CI)= NCH 2 Ph(R = CF 3,CFCI 2,C 3 F 7,t Bu,Ar)的光化学氯化导致RC(CI)= NCH(CI)Ph或其混合物取决于取代基R的性质,其具有RCCI 2 N = CHPh的异构体。已经观察到并研究了氯化产物中的1,3-丙酸和1,3-氯酸重排。
ISOMERIZATION OF TRIFLUOROACETIMIDOYL CHLORIDES AND THEIR 1,3-DIPOLAR CYCLOADDITIONS WITH ELECTRON-DEFICIENT OLEFINS
corresponding N-trifluoroethylbenzimidoyl chlorides under more drastic conditions. The reactions of the trifluoroacetimidoyl chlorides with methyl acrylate and acrylonitrile give the corresponding 1,3-dipolar cycloadducts.
The Staudinger reaction of fluoroalkylazides were studied. A series of N-fluoroalkylimines were synthesized via aza-Wittig reaction of N-fluoroalkyliminophosphoranes. The N,N'-difluoroalkylated carbodiimide was also synthesized via the reaction of N-fluoroalkyliminophosphoranes with carbon dioxide or carbon disulfide. (c) 2006 Elsevier B.V. All rights reserved.
