Numerous new metal halide, carbonyl, and cyclopentadienyl complexes of the chelating tritertiary phosphine bis(2-diphenylphosphinoethyl) phenylphosphine and the chelating tetratertiary phosphines 1,1,4,7,10, 10-hexaphenyl-1,4,7,10-tetraphosphadecane and tris(2-diphenylphosphinoethyl) phosphine are described. Some preliminary studies of reactions of metal carbonyl derivatives with diphenylvinylphosphine are discussed. Metal complexes of the acetylenic tertiary phosphines (C6H5)2PCH2CCCH2P(C6H5)2 and (C6H5)2PCCC6H5 are described. A few reactions of tris(dimethylamino)arsine with various metal carbonyls are summarized; these resulted in the preparation of the first derivative with two tris(dimethylamino)arsine ligands attached to a single metal atom. The mixed phosphine-isonitrile and arsine-isontrile ligands (C6H5)2ECH2CH2NC(E = P or As) have been prepared by the base-catalyzed addition of (C6H5)2EH(E = P or As) to vinyl isocyanide; these are the first known compounds containing both tertiary phosphine (or arsine) and isonitrile groups. Some new compounds have been obtained from pentacarbonyliron and the diacetylenes 1,7-cyclotridecadiyne, 1,8-cyclotetradecadiyne, and 2,4-hexadiyne. Possible aerospace applications of this research are discussed. (Author).
