Un nouveau type de dimère de phosphole incorporant un cycle à sept chaînons. La réaction de la. N-bromosuccinimide avec un équivalent du dérivé lithié du 1-phényl-3,4-diméthylphosphole-borane (1) conduit à un nouveau type de dimère de phosphole (2). L'analyse structurale aux rayons X montre une jonction C α (phosphole)-CH 2 -C β (phosphole) et un carbocycle à sept chaînons.
The reaction of N-bromosuccinimide with one equivalent of the lithium derivative of the 1-phenyl-3,4-dimethylphosphole-borane adduct (1) produces a new type of phosphole dimer (2). The X-ray crystal structure analysis shows a seven-membered carbocycle and a C α (phosphole)-CH 2 -C β (phosphole) junction.La reaction de la N-bromosuccinimide avec un equivalent du derive lithie...
