A facile hydride transfer from hydrosilane to a borinic acid is efficiently mediated by a tertiary amine. This led to the development a mild reduction of carbonyl derivatives by using phenylsilane and catalytic amount of borinic acid and amine.

The silylium ion promoted reduction of imines yielding the correspondingamines is reported. Both tert-butylferrocenylmethylsilane and triethylsilane are efficient hydride donors for the reduction of intermediate silyliminium ions, thereby regenerating the catalytically active silylium ion and closing the catalytic cycle.
New fluorinating reagents. Part II. Preparation and Synthetic Application of a Saccharin DerivedN-Fluorosultam

日期:1989.9.20
The synthesis of the new saccharin derived N-fluorosultam 1 is described. A comparative study with commercially available N-fluorosulfonamides shows 1 to be a superior fluorinating reagent for the synthesis of α-fluorocarbonyl compounds.
