The acceptor properties towards some Lewis bases of the perchloroalkylchlorophosphoranes P(CCl3)Cl4, P(CCl3)2Cl3, P(C2Cl5)Cl4 and of their salts with strong Lewis acids, have been investigated by means of 31P n.m.r. spectroscopy.The results are compared with those for other alkyl- and aryl-chlorophosphoranes. Key words: Acceptor (properties); phosphoranes (perchloroalkylchloro); Lewis acid (derivatives).
Some Novel Phosphoranides containing Pentafluorophenyl Groups

Several novel phosphoranides containing pentafluorophenyl groups, of formulae - (X= Cl, Y= Cl, Br, or I; X= Br, Y= Br or I; X= NCS, Y= Cl, Br, I or NCS) or - (X= Cl, Y= Cl, Br, or I; X= Br, Y= Br or I; X= CN, Y= Cl, Br, I, or NCS) have been identified in solution by means of 31P n.m.r. spectroscopy.Most of the species have been isolated as salts with tetra-alkylammonium ions, and further characterised by elemental analysis and (in some cases) i.r. spectroscopy.These ions -> represent the first simple phosphoranides with an organo-group attached to phosphorus and no cyano-groups present.The species with two pentafluorophenyl groups are the first phosphoranides with two organo-groups directly bound to phosphorus.No acceptor properties towards halide ions were shown by P(CCl3)Cl2 or P(C6F5)2(NCS).
