Usage

Uses

Chlorodi(o-tolyl)phosphine is an important raw material and intermediate used in organic synthesis, pharmaceuticals, agrochemicals and dye stuff.

Purification Methods

It is purified by fractional distillation in a vacuum (b 179-183o/7mm, 253-257o/15mm,) and the distillate solidifies (m 36o, also reported is m 37o). [Weinberg J Org chem. 40 3586 1975, McEwen et al. J Am Chem Soc 100 7304 1978, Beilstein 16 H 769, 16 IV 970 for chlorodi(p-tolyl)phosphine.]

The starting material chlorodi(o-tolyl)phosphine has been prepared by the reaction of phosphorus trichloride and the Grignard of o-chlorotoluene.The intermediate lithium di(o-tolyl)phosphide was obtained by the direct reaction of lithium metal and chlorod

Method for preparing diarylphosphoryl chloride compound

The invention discloses a method for preparing a diarylphosphochlorine compound and belongs to the field of organic synthesis. The method is as follows: the diarylphosphochlorine compound is preparedby reaction of triarylphosphine as a starting material with phosphorus trichloride in the presence of zinc trifluoromethanesulfonate as a catalyst and distillation. Compared with the prior art, the method has the advantages of high reaction yield and simple post-treatment, is particularly suitable for preparation of the diarylphosphochlorine compound with a substituent, and is more suitable for industrial production. The obtained diarylphosphochlorine compound can be used as a ligand for synthesizing metal catalysts, and is applied to the fields such as organic photoelectric materials and medicines.

TETRAMERISATION OF ETHYLENE

A process for the tetramerisation of ethylene includes contacting ethylene with a catalyst under ethylene oligomerisation conditions. The catalyst comprises a source of chromium, a ligating compound, and an activator. The ligating compound includes a phosphine that forms part of a cyclic structure.
