Ultrasonic Acceleration of Organic Reactions, by sonolysis of the Cu (gly). and the relevant chloride at pH 11.0. The process was similarly successful in the case of .chlor- benzyl chloride, but only gave 5% of the TV-arylmethylated product in the case where R = .-Me [176] (Scheme 79).

The Effects of Ultrasound on Transition Metal Catalysts,case of the palladium blacks. There is no obvious explanation for this. A similar technique was used to prepare suspensions of platinum on silica gel. Hence, reduction of solutions of platinum complexes in the presence of ultrasound (440 kHz, 5 Wcm.) increased the available surface area of platinum
