A copper-catalyzed protocol for reductive methylation of amines and imine with formic acid as a C1 source and phenylsilane as a reductant is reported for the first time, affording the corresponding methylamines in good to excellent yields under mild conditions. This protocol offers an alternative method for indirect utilization of CO2, as formic acid can be readily obtained from hydrogenation of CO2

The present invention relates to a specific process for preparing organosilane esters of the formula (I) and a composition comprising more than 98% by weight of organosilane esters of the formula (I) and less than 2.0% by weight of at least one hydrocarbon and to the use of such a composition as precursor for producing a layer or film having a dielectric constant of 1 < κ ≤ 4.
