Rhodium catalysed asymmetric hydroformylation with chiral diphosphite ligands

Chiral diphosphites have been synthesised starting from 1,2:5,6-diisopropylidene-D-mannitol, L-alpha,alpha,alpha,alpha,-tetramethyla-1,3-dioxolan-4,5-dimethanol and L-diethyltertrate. The diols react in moderate to good yields with 2,2′-bisphenoxyphosphorus chloride and 4,4’6,6′,-tetra-t-butyl-2,2′-bisphenoxyphosphorus chloride (32-92%) to the corresponding chiral diphosphites. The compounds all exhibit C2 symmetry and have been used as ligands in the rhodium catalysed asymmetric hydroformylation of styrene. The catalytic activity of the diphosphites strongly depends on the bulkynes of the ligand. With a bulky ligand enantiomeric excesses up till 20% have been obtained under mild reaction conditions (25-40C, 40 bar syngas). It was found that both enantiomeric excess and regioselectivity to the branched aldehyde strongly depend on the hydroformylation reaction conditions.

Synthesis, structural characterization and dielectric behavior of new oxime-cyclotriphosphazene derivatives

The cyclotriphosphazene compound (2) bearing formyl groups as side groups was obtained from the reaction of 2,2-Dichloro-4,4,6,6-bis[spiro(2?,2?-dioxy-1?,1?-biphenylyl)]cyclotriphosphazene (1) with 4-hydroxy-3-methoxybenzaldehyde in the presence K2CO3 in tetrahydrofuran. Oxime-cyclotriphosphazene compound (3) was synthesized from the reaction of compound 2 with hydroxylamine hydrochloride in pyridine. The synthesized oxime-phosphazene compound (3) was reacted with alkyl and acyl halides. As a results, the cyclotriphosphazene compounds (1-10) bearing oxime ether and ester as side groups were obtained. The chemical structures of these compounds (1-10) were determined by elemental analysis, FT-IR, 1H, 13C and 31P NMR spectroscopic methods. Dielectric constant, dielectric loss factors and conductivity properties of cyclotriphosphazene compounds were measured over the frequency range from 100 Hz to 2 kHz at 25C and compared with each other. It is found that ester substituted cyclotriphosphazenes have higher dielectric constant. Our study suggests that these phosphazenes promising candidate materials in multifunctional optoelectronic devices.
