Chiral phase transfer catalysis,re, in general, not expensive, are easy to prepare and can be used for large- scale reactions. If the desired reactions proceed sluggishly, addition of a small amount of a phase transfer catalyst might accelerate the reactions in a number of cases. However, asymmetric reactions utilizing chiral phas

Phase transfer catalysis of uncharged species,. However, a secondary mechanism has been observed in several systems where the extraction is the outcome of nonstoichiometric hydrogen-bonded complex formed between the substrate and the anion of the quaternary ammonium ion pair (equation 16.1).

Still, the history of comic book movies is a long one, and can be traced to the very earliest days of the motion picture medium. In this book, we will consider, for the most part, those mo
