  Tetraphenylphosphonium carboxylates and sulfonates. Synthesis and structure

  摘要：

  The reaction of the pentaphenyphosphorus solvate Ph5P center dot 1/2PhH (I) with carboxylic and sulfonic acids was used to synthesize tetraphenylphosphonium carboxylates Ph4POC(O)R, R = C6H4(2-OH) (II), C6H4 (2-COOH) (III), H (IV), Me (V), CCl3 (VI), Ph (VII), PhCH=CH (VIII), CH2CH2C(O)OH (IX), CH=CHC(O) OH(X), and CH2C(O)OH (XI) and tetraphenylphosphonium sulfonates Ph4POSO2Ar, Ar = Ph (XII), C6H4Me4 (XIII), and C6H3(-COOH)(4-OH) (XIV). Compound XII was also prepared from compound I and SO3 in benzene. According to X-ray diffraction data, the crystals of I contain two types of crystallographically independent molecules with a slightly distorted trigonal-bipyramidal configuration [Ia, CaxPCax 178.44(8)A degrees, P- C-ax 1.985(2), 1.987(2) A..., P-C-eq 1.854(2), 1.846(2), 1.840(2) A...; Ib, CaxPCax 178.45(9)A degrees, P-C-ax 1.980(2), 1.975 (2) A..., P-C-eq 1.840(2), 1.846(2), 1.854(2) A...]. In the cations of compounds II, III and XIV, the coordination of the phosphorus atom is tetrahedral [CPC angle: II, 106.2(2)-111.6(1)A degrees; III, 104.01(6)-113.03(6)A degrees; XIV, 107.54 (6)-112.79(6)A degrees]; the anions contain intramolecular O-Ha <-O hydrogen bonds between the hydroxyl hydrogen atom and carboxyl oxygen atom (II, 1.34; III, 1.23; and XIV, 1.83 A...).

  Provided are an aromatic polycarbonate copolymer and a method for producing it. An aromatic dihydroxy compound, at least one member selected from the group consisting of polyorganosiloxanes and aliphatic polyalcohols, and a dicarbonate are prepolymerized under heat to give a polycarbonate prepolymer, and the prepolymer is polymerized in a solid or swollen solid phase in the presence of a quaternary phosphonium salt serving as a catalyst to give an aromatic polycarbonate copolymer. The remaining monomer content, the acetone soluble content (that is, the low-molecular-weight substance content) and the cyclic oligomer content of the copolymer are all reduced, and the terminal hydroxyl fraction thereof is also reduced.
