Formation of acylsilenolates from Bis(acyl)trisilanes as the silicon analogues of acylenolates

Reactions of bis(acyl)trisilanes with tris(trimethylsilyl)silyllithium in THF, followed by treatment of the resulting dark red solutions with alkyl halides, gave the Si-alkylated products and tetrakis(trimethylsilyl)silane, indicating the formation of lithium acylsilenolates via Si-Li exchange. Exothermic formation of lithium acylsilenolate was demonstrated by DFT calculations on a model reaction.

(2,4,6-Trimethylbenzoyl)diphenylphosphine oxide photochemistry. A direct time-resolved spectroscopic study of both radical fragments

The photochemistry of (2,4,6-trimethylbenzoyl)diphenylphosphine oxide (1) has been investigated using time-resolved infrared (TRIR) and time-resolved UV spectroscopy (laser flash photolysis (LFP)), in addition to conventional photochemical steady-state te
