Applicazioni

Bismuth(III) chloride is used as a catalyst in organic synthesis and to prepare other bismuth salts. It is used as a starting material for the preparation of bismuthoxychloride upon hydrolysis. It is an oxidizing agent to prepare metallic bismuth by reducing agent. Further, it catalyzes the Michael reaction and the Mukaiyama-aldol reaction. In addition to this, it is a Lewis acid.

Note

Hygroscopic. Incompatible with strong oxidizing agents.

Silyl enol ethers can be ɑ-acylated with acyl chlorides in the presence of a catalytic amount of BiCl3 and NaI or ZnI2; other Lewis acids such as ZnCl2 were less effective: J. Org. Chem., 61, 3885 (1996).
