Lithium diphenyl cuprate
WebThe chloroselenurane salt ( 31) reacts with either lithium dimethyl cuprate or lithium diphenyl cuprate to give the corresponding Se -methylammonioselenurane and Se -phenyl-ammonioselenurane. Reaction of the selenoxide of ( 30) with one equivalent of trimethylsilyl triflate gives the corresponding hydroxylamino selenurane < 92JCS (P1)2247 >. WebBromobenzene reacts with L i and C u I to form Lithium, diphenyl cuprate. It then reacts with butyryl chloride to form 1-phenylbutan-1-one. The − C l atom of acid chloride is replaced with phenyl group. In the last step, the carbonyl group is reduced to methylene group by Clemmensens reduction with zinc amalgam and conc H C l.
