Webof Pearlman’s catalyst required no stabilizing phos-phate buffer [19–21], however, to achieve high yields it was crucial that the products were only allowed to stay in solutionfor the minimumtime necessary. Thus, the organosilanols were isolated immediately when the evolution of hydrogen gas ceased, indicating that the reaction was complete.
