| Hazard Information | Back Directory | [Uses]
Diethyl[dimethyl(phenyl)silyl]aluminum can silylaluminate terminal alkynes;can cross couple with
alkenyl, allyl, and aryl phosphates;can deoxygenate epoxides.
The reagent adds
to 1-alkynes in a regio- and stereoselective (cis addition) manner.
Transition metal catalysts alter the regioselectivity (eq 1).
| [Preparation]
prepared in situ by adding PhMe2SiLi in
THF to a hexane solution of Et2AlCl at 0°C. |
