Numerous new metal halide, carbonyl, and cyclopentadienyl complexes of the chelating tritertiary phosphine bis2-diphenylphosphinoethyl phenylphosphine and the chelating tetratertiary phosphines 1,1,4,7,10, 10-hexaphenyl-1,4,7,10-tetraphosphadecane and tris2-diphenylphosphinoethyl phosphine are described. Some preliminary studies of reactions of metal carbonyl derivatives with diphenylvinylphosphine are discussed. Metal complexes of the acetylenic tertiary phosphines C6H52PCH2CCCH2PC6H52 and C6H52PCCC6H5 are described. A few reactions of trisdimethylaminoarsine with various metal carbonyls are summarized these resulted in the preparation of the first derivative with two trisdimethylaminoarsine ligands attached to a single metal atom. The mixed phosphine-isonitrile and arsine-isontrile ligands C6H52ECH2CH2NCE P or As have been prepared by the base-catalyzed addition of C6H52EHE 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
