Ultrasonic Acceleration of Organic Reactions,nometallic systems and a number of useful procedures for transformations involving non-metals have been published. For instance, amines can be iV-alkylated by alkyl halides in the presence of potassium hydroxide and a phase transfer catalyst . .-benzyl glycine was readily prepared in high yield

Ultrasonic Acceleration of Redox Reactions,ctions that would more commonly be executed under homogeneous conditions. For instance, the reduction of aryl halides with lithium aluminium hydride occurs extremely slowly in THF solution. However, Han and Boud- jouk have reported that the reaction can be carried out in a fraction of the time if th

The Effects of Ultrasound on Transition Metal Catalysts,. However, it has also been clearly shown that palladium and platinum blacks prepared by reduction of the metal salts in the presence of formaldehyde had up to 30% greater surface areas and showed increased activity in a number of representative reactions. These included the decomposition of wa

Transition Metal Carbonyls and Ultrasound, to be available from a variety of substrates . For example, they may be prepared from alkenyl epoxides or various butenediols and their derivatives by treatment with tetracarbonyl iron . Work in our laboratories had shown that these were useful precursors for a wide range of natural
