Tris(2-pyridyl)phosphine: a straightforward microwave-assisted synthesis from 2-bromopyridine and red phosphorus and coordination with cobalt(ii) dichloride
Аннотация:
Microwave irradiation of 2-bromopyridine with red phosphorus in the superbasic KOH/DMSO (H2O) suspension affords tris(2-pyridyl)phosphine in 53% yield; two molecules of tris(2-pyridyl)phosphine coordinate with CoCl2 by their six nitrogen atoms only to form [Co(2-Py3P)2]Cl2⋅8H2O complex having two phosphorus atoms beyond the coordination sphere.
