A series of functional organosilanes and their esters were synthesized by the hydrosilylation reaction of SiH group‐bearing organosilicon derivatives with maleic anhydride using Speier's catalyst and their esterification with long‐chain alcohols in the presence of stannous oxide. These products have been characterized using elemental analysis, FT‐IR, 1 H, 13 C and 29 Si NMR. Viscosity, density, pour point, flash point and tribological properties of these compounds have also been evaluated. These esters have a pour point of <−60 °C, a flash point of ∼200 °C (closed‐cup) and excellent load carrying capacity. Copyright © 2009 John Wiley & Sons, Ltd.
