Difunctional halo silicon amide compounds are prepared by cleaving the nitrogen-silicon bond in a nitrogen-silicon heterocycle with a reactive halide. The reaction is straight forward with no intermediates or byproducts. The halo functionality is capable of capping any SiOH group. When the other functionality is an acrylamide, the capped entity may be polymerized or crosslinked by free radical initiators of the acrylamide functionality thereby producing useful products such as paper release coatings and photoresists.
