The Lewis acid properties of B(CH 3) 3 have been analyzed by the ECW model yielding E A = 2.90 and C A = 3.60. When trimethylborane forms an adduct with trimethylamine, steric repulsion between the methyl groups on the B and N results. The ECW model can provide a measure of this steric effect.
The structure of a typical methoxy group. In organic chemistry, a methoxy group is the functional group consisting of a methyl group bound to oxygen.This alkoxy group has the formula R−O−CH 3.
2,2-Dimethoxypropane (DMP) is an organic compound with the formula (CH 3) 2 C(OCH 3) 2.A colorless liquid, it is the product of the condensation of acetone and methanol.DMP is used as a water scavenger in water-sensitive reactions.
The enthalpy data show that AlMe 3 is a hard acid and its acid parameters in the ECW model are E A =8.66 and C A = 3.68. These adducts, e.g. the complex with the tertiary amine DABCO , are safer to handle than TMA itself.

Tetramethyl orthosilicate (TMOS) is the chemical compound with the formula Si(OCH 3) 4.This molecule consists of four methoxy groups bonded to a silicon atom. The basic properties are similar to the more popular tetraethyl orthosilicate, which is usually preferred because the product of hydrolysis, ethanol, is less toxic than methanol.
