[ReBr(CO)5] reacted with phosphinite or phosphonite ligands in benzene or toluene to yield fac-(1) or mer,trans-(2) complexes, ([ReBr(CO)3(L)2] L = PPh2(OMe), a; PPh2(OEt), b; PPh(OMe)2, c; PPh(OEt)2, d) characterized by elemental analysis, mass spectrometry, IR and NMR (1H, 13C and 31P) spectroscopies, and for complexes 1b, 2c and 2d, X-ray diffractometry was used. Complexes 2a-2d reacted with Ag[BF4] in wet acetone to form moderate yield of mer,trans-[Re(H2O)(CO)3(L)2][BF4] (3). Comparison of the spectra of compounds 3 with those of precursors 2 together with the diffractometric results for compounds 3a-3c, show that all the complexes have the same configuration around the rhenium atom. Crystals of compounds 3 consist of centrosymmetric dimers formed by hydrogen bonds between the water molecules and the BF4- anions. The lability of compounds 3 was explored by 19F and 31P NMR, and in the case of 3c the complex [Re(nu1-BF4)(CO)3 {PPh(OMe)2}2] (4c) was isolated from the mother liquor. Spectroscopic and diffractometric studies of 4c show monodentate coordination of the tetrafluorborato ligand to the rhenium atom.

Pyrolysis of 2,2-diphenyl-2-methoxy derivatives of the title compounds in the gas phase gives phosphinates or phosphinamidates derived from the substrate by formal loss of methylene.Control experiments show that the reaction involves radical cleavage initiated by rupture of the oxazaphosph(V)ole ring.Pyrolysis of 3-aryl-2,2-dimethoxy-2-phenyl derivatives of the title compounds under similar conditions results in the formation of 3-aryl-2,3-dihydro-2-oxo-2-phenyl-1,3,2-benzoxazaphospholes.No significant products could be isolated from 2,2,2-trimethoxy derivatives, though vigorous conditions were required for their complete breakdown.The pyrolysis of the corresponding 2,2-diphenyl-2-ethoxy, 2,2-diethoxy-2-phenyl, and 2,2,2-triethoxy compounds gave higher yields of similar products, possibly via a six-centre concerted elimination.

In sharp contrast to tetraphenyldiphosphine, which does not add to carbon?carbon double bonds efficiently, its monoxide, [Ph2P(O)PPh2] can engage in a radical addition to various alkenes, thus affording the corresponding 1-phosphinyl-2-phosphinoalkanes regioselectively, and they can be converted into their sulfides by treatment with elemental sulfur. The phosphinylphosphination proceeds by the homolytic cleavage of the PV(O)?PIIIsingle bond of Ph2P(O)PPh2, followed by selective attack of the phosphinyl radical at the terminal position of the alkenes, and selective trapping of the resulting carbon radical by the phosphino group. Furthermore, the phosphinylphosphination product could be converted directly into its platinum complex with a hemilabile P,O chelation.

A practical procedure for the selective preparation of KHCr(CO)5 is described. The use of a potassium cation in the coordination chemistry of the [HFe(CO)4]- anion is completed and extended to the coordination chemistry of the [HCr(CO)5]- anion: CO-substitution by phosphites, phosphines and phosphinites, and H-abstraction by aminophosphines. Most of the observed differences in reactivity between KHFe(CO)4 and KHCr(CO)5 can be rationalized by the stronger acidity of KHFe(CO)4.
