Syntheses, structures, and catalytic ethylene oligomerization behaviors of Bis(phosphanyl)aminenickel(II) Complexes containing N-functionalized pendant groups

Several N-functionalized bis(phosphanyl)amine ligands respectively containing benzyl, furfuryl, thiophene-2-methyl, thiophene-2-ethyl, and 2-picolyl groups (la-e) were synthesized and characterized. The ligands reacted with (DME)NiBr2 in CH2Cl2 to give their corresponding nickel complexes [Ph2PN(R)PPh2NiBr 2] [R = CH2C6H5 (2a), CH 2C4H3O (2b), CH2C4H 3S (2c), CH2C5H4N (2d), and CH 2CH2C4H3S (2e)], The structures of these complexes were established by single-crystal X-ray crystallography, All these nickel complexes were highly active towards ethylene oligomerization in the presence of methylaluminoxane or Et2AlCl, producing a high content of butene (C4), Especially for 2e, which contains a thiophene-2-ethyl pendant group, the oligomerization products obtained at -40 °C contained 95.9 mol-% C4 fraction with 100 mol-% 1-butene. Over 50 °C, however, these nickel complexes underwent: Friedel-Crafts alkylation of toluene with ethylene and the olefin oligomers.

Process for the preparation of substituted vinylbenzyl chloride

An improved continous single step vapor phase process for the preparation of substituted vinylbenzyl chloride from substituted ethyltoluene is disclosed. In this process a substituted ethyltoluene is reacted with a halogen gas in the vapor phase, at elevated temperatures via a continuous feed process. Furthermore, this process achieves halogenation followed by dehydrohalogenation in a single pass through the reactor. There is also obtained a very high total selectivity to vinylbenzyl chloride and its precursors via this continuous process.
