Unexpected Silicon Group Transfer in Difunctional Alkoxy Silanes
摘要:
During the hydrosilylation reaction of a difunctional silane with allyl glycidyl ether (AGE), two scrambled hydrosilylation products were produced in significant amounts. This scrambling is reaction condition dependent and has been observed in a few other examples. It appears to be the first such alkoxysilane transformation to occur under these conditions, although similar siloxane transformations have been documented. This also introduces a method of preparing certain organofunctional alkyldialkoxysilanes in high purities via hydrosilylation, where the close boiling rearrangement by-products are minimized.
