Copper Catalysis in the Methylenation of Arsenic Trichloride and Arsenic Tribromide.
Abstract
Dramatic increases in yields of methylene-insertion products in the reactions of diazomethane with arsenic trichloride and arsenic tribromide were achieved through the use of copper catalysis. Mono- and bis-insertion products, XCH2AsX2 and (XCH2)2AsX (X = Cl or Br), but no tris-halomethyl arsines were obtained. The success of the procedure depends upon the use of ether solvent reclaimed from previous reactions.
