C₆H₅PBr₂Cr(CO)5

Guidance literature:: With tetrahydrofuran; In toluene; Irradiation (UV/VIS); (N2); soln. of Cr(CO)6 and THF was irradiated for 24 h, then a less than equimolar amt. of P-ligand in toluene was added dropwise and mixt. was stirred for a few h; major part of solvent was evapd. and residue chromd. (alumina, toluene), crystals are obtained by slow evapn. of the eluate in vac. at room temp.;
