Interaction of E-2-dibutylboryl-1-phenyl-1-diphenylphosphinohex-1-ene with diphenylketene and benzoyl(phenyl)diazomethane

A new betaine, 5,6,6-tributyl-2-diphenylmethylene-3,3,4-triphenyl-1-oxa-3-phosphonia-6-boratacyclohex-4-ene, and1-(benzoyl(phenyl)methyleneamino]-4,5,5-tributyl-2,2,3-triphenyl-2-phospha-I-azonia-5-boratacyclopenta-1,3-diene were synthesized upon interaction of E-2-dibutylboryl-1-phenyl-1-diphenylphosphinohex-1-ene with diphenylketene and benzoyl(phenyl)diazomethane, respectively. The structure of the latter product was established by IR spectroscopy and X-ray structural analysis.

The complexation of (N,N-diethylcarbamoylmethyl)diphenylphosphine sulfide with silver nitrate

The crystalline complex [Ag(L1)NO3]2 (A) was isolated by the interaction of (N,N-diethylcaibamoylmethyl)diphenylphosphine sulfide Ph2P(S)CH2C(O)NEt2 (L1) with AgNO3 in different solvents at the ratios of metal:ligand = 1∶1 and 1∶2. According to the X-ray data, complexA is a center-symmetric dimer with bridge sulfur atoms. The cations of the metal are in a tetrahedral environment formed by two S atoms and the O atoms of CO and NO3 groups. The interaction ofL1 with AgNO3 was studied in solution by IR spectroscopy, and the structures of the complexes formed are discussed.

Synthesis and some properties of planar 4-diphenylphosphino-1,3,2-dioxaborinanes

Fused 1,3,2-dioxaborinanes, derivatives of 4-diphenylphosphino- and 4-diphenylphosphoryl-4H-1, 3-dioxa-2-boraphenanthrenes, and their complexes with amines have been synthesized. According to X-ray diffraction data, the complex of 2-phenyl-4-diphenylphosphoryl-4H-1, 3-dioxa-2-boraphenanthrene with butylamine exists as a dimer due to the formation of intermolecular hydrogen bonds.
