THALLIUM (I) ETHOXIDE Chemical Properties,Usage,Production

Chemical Properties

cloudy, dense liquid; sensitive to moisture [STR93]

Uses

Thallium Ethoxide is used as a catalyst in suzuki cross coupling reactions.

Uses

With HCl, reduces a variety of functional groups; stereoselective allylation of carbonyl compounds; in situ generation of tin enolates for directed aldol reactions.

Safety Profile

Poison by ingestion. When heated to decomposition it emits toxic fumes of T1. See also THALLIUM COMPOUNDS
