This arose historically from early studies which concentrated almost exclu­ sively on reactions in aqueous media and was also, in some measure, due to the availability of suitable t

The Physical Basis of Sonochemistry, present a qualitative overview in an attempt to clarify this subject which tends to be regarded as something of a black art! For a more detailed report, interested readers are referred to Suslick’s recently published review which deals comprehensively with this aspect of sonochemistry [3, 4].

Preparation of Organoaluminium Compounds,nvolves use of Al—Mg alloys, proved unnecessary. Recent work has shown that organoaluminium species of the type R.A1.X. are available via reaction of alkyl halides with aluminium powder [80] (Scheme 18), although yields of subsequent reactions are poor.

CREST

Intercalation Reactions,, synthesis of such compounds generally requires the use of extremely high temperatures over very long periods of time. In contrast, sonicating the reaction mixture brings the reaction to completion within hours, rather than the days required for the thermal reaction.

Preparation of Activated Magnesium,vertheless, there are a number of organic halides which continue to give unsatisfactory results under these reaction conditions. As a result, much effort has been invested in examining other methods for activating the metal.
