Abstract

Abstract Starting from R′ R 2 P (R′= 8-dimethylamino-1-naphthyl) containing a donor dimethylamino group, the new phosphonium salts [R′ R 2 P (CH 2 Ph)]+ Br–[R= Me (9) or Ph (10)] and [R′ R 2 P (p-CH 2 C 6 H 4 CH 2) PR 2 R′] 2+[2Br] 2–[R= Ph (12)] have been prepared. An interaction between the N and P atoms is evident from the X-ray crystal structure of 10 the N–P distance being less than the sum of the van der Waals radii of the ...
