Nonvolatile Me3P-like P-Donor Ligand: Synthesis and Properties of 4-Phenyl-1-phospha-4-silabicyclo[2.2.2]octane
摘要:
[GRAPHICS]A new trialkylphosphine ligand with Me3P-like steric and electronic properties, 4-phenyl-1-phospha-4-silabicyclo[2.2.2]octane (Ph-SMAP), was synthesized. Given a phenyl group at the silicon atom, the Ph-SMAP ligand displayed nonvolatility with retention of Me3P-like properties. The new ligand was air-stable, crystalline, and easy to handle.

A composition contains (A) a hydrosilylation reaction catalyst and (B) an aliphatically unsaturated compound having an average, per molecule, of one or more aliphatically unsaturated organic groups capable of undergoing hydrosilylation reaction. The composition is capable of reacting via hydrosilylation reaction to form a reaction product, such as a silane, a gum, a gel, a rubber, or a resin. Ingredient (A) contains an iron-organosilicon ligand complex that can be prepared by reacting an iron carbonyl compound and an organosilicon ligand.

In this paper the synthesis of new iron(0) carbonyl complexes with π-bonded ligands containing at least two silicon-vinyl groups of formula [Fe(CO)3L] and [Fe(CO)3}2L′] are described. The synthesis is done via UV light initiated substitution of carbonyl ligands in [Fe(CO)5] or [Fe2(CO)9] precursors by organosilicon dienes, trienes, vinyl functional silicones (L), tetraenes (L′). The spectroscopic

A photoinduced cationic polycondensation towards the synthesis of a thieno[3,4-b]thiophene (TT) based homopolymer PTT-L was described. The reaction mechanism was investigated by employing a series of control experiments. It was found that the polymerization initiated with a light-induced radical formation, followed by a cationic propagation, all in solid state, at room temperature, and without any

or three Lewis-acidic sidearms. With the aim of providing host-guest complexes, the air-stable and readily soluble compounds 5–8 were converted with N- and O-Lewis bases of different size and geometry. In all cases, NMR spectroscopic investigations reveal no formation of Lewis acid-base complexes. X-ray diffraction experiments of host compounds 5–7 show intermolecular aryl…perfluoroaryl interactions
