Studies on the conditions of aerobic [Co] or [Cu] / NHPI -
catalyzed oxidation of hydride siloxane 1a to siloxanol 2а
allowed us to find the most efficient conditions for the
oxidation of mono-, oligo- and polymeric siloxanols hydride
siloxanes 1a-i with various structures (linear, branched and
cyclic) in gram amounts (0.5 – 11 g).
Thus, considering the simplicity and efficiency of the catalytic
reaction and taking into account the commercial availability
and the low cost of the reagents used, this method has
considerable prospects for application in the synthesis of
complex molecular systems with desired structures as well as
new organosilicon monomers, oligomers and polymers.
