Synthesis
67-56-1
775-12-2
6843-66-9
General procedure: the synthesis was carried out using a standard catalytic CDC reaction scheme. In an inert atmosphere glove box, the precatalyst (0.05 mmol) was accurately weighed and added to a Schlenk tube, followed by the sequential addition of methanol (n × 0.05 mmol, n-equivalent) and diphenylsilane (n' × 0.05 mmol, n' equivalent). The reaction mixture was placed in a 30°C oil bath with constant temperature stirring for the reaction. Upon completion of the reaction, the reaction was quenched by the addition of CDCl3. The reaction mixture was analyzed using 1H NMR spectroscopy and the reaction conversion was monitored by comparing the relative intensities of the characteristic peaks of the substrate and the product.
