Hydrosilylation of carbonyls catalyzed by 2 goes via intermediate formation of cationic silane sigma-complexes 4 which undergo nucleophilic abstraction of the silylium cation studied by DFT calculations.

We report a catalytic reductive alkylation reaction of primary or secondary amines with carboxylic acids. The two-phase process involves silane mediated direct amidation followed by catalytic reduction.

The silylium ion-catalysed reduction of carbonyl compounds to the alcohol oxidation level is accomplished by exploiting the unique reactivity of a ferrocenyl-substituted silane.

A copper-catalyzed domino reaction between itaconate esters and diethyl zinc (or silane) is developed, affording itaconate dimerization products, multi-ester-substituted cyclopentanones, in moderate to high yields.

In order to calculate the redis tr ibut ion of boron in silicon by both diffusion and autodoping dur ing epitaxial growth, certain materials parameters must be known as a function of temperature. The parameters are the diffusion coefficient of boron, the evaporat ion coefficient of boron from silicon, and the silicon evaporation rate in a hydrogen ambient. The value of the diffusion coefficient...

Aqueous chemistries have recently been shown to be useful for the deposition of hydrophobic films of nonionic and cationic silanes on hydrophilic substrates for the prevention of stiction in MEMS. The Monte Carlo method is used to simulate in two dimensions the self-assembly of silane films on a hydrophilic surface. We investigate the impact of charged group in cationic silane on the overall st...

Depositing a fused-ring thieno-thiophene polymer on different self-assembled monolayers indicates that varying the SAM surface energy changes the FET mobility and turn-on voltage by varying polymer crystallinity at the buried interface.
