Abstract

Under 254 nm irradiation in chloroform, Bi(C6H5)3Cl2 reacts to yield HBiCl4 and H2BiCl5, in contrast to its behavior in acetonitrile, in which bismuth metal appears to be the eventual product, unless anhydrous HCl is present, in which case H2BiCl5 is also formed. The photolysis in CHCl3 is not significantly solvent-initiated. The rate depends directly on the light intensity absorbed by the metal complex, and the quantum yield is 0.026. In CCl4 a portion of the reaction occurs through absorption of light by the solvent.
