- Silicon-oxygen moiety (Si-O) is one of the most important chemical scaffolds, starting with its role in nature as a major constituent of Earth’s crust, and finishing on its usefulness in terms of a broadly understood practicability for the industry. This second issue refers primarily to siloxanes including both short and long- chained derivatives. To date, the classical condensation between different O-nucleophiles (e.g., water, alcohols, silanols, etc.) and halosilanes appears to be the most useful, large-scale method for their obtainment. However, the issues related to low chemoselectivity and low sustainability of these processes have caused an extensive exploration of more selective and milder alternatives. Herein, several methods for the formation of unsymmetrical siloxanes are discussed including these based on the cleavage of silicon-hydrogen or silicon- carbon bonds in the presence of silanols and proper catalysts/mediators.
