| Hazard Information | Back Directory | [Uses]
B-Chlorocatecholborane can be used:
- To prepare 2-arachidonoylglycerol by acetal cleavage of cis-arachidonoylbenzylidene glycerol.
- To prepare metal boryl complexes (Rh and Ir complexes) through oxidative addition.
- To remove the trityl group in one of the key steps for the synthesis of (?)-dictyostatin.
| [General Description]
B-Chlorocatecholborane is a boron reagent and a Lewis acid, known to facilitate the borylative cyclization of alkynes to yield the borylated heterocycles. It is also used in the preparation of lactones, and thiophenes. |
