Bifurcations and Routes to Chaos,equipment is only occasionally required and there is rarely any need for the extremes of pressure and temperature synonymous with older industrial carbonylation processes. Small-scale atmospheric pressure procedures can in fact often be carried out in conventional laboratory glassware. In procedural

Pattern Formation and Spatiotemporal Chaos,ntrinsic value of aldehydes as synthetic intermediates but also the scarcity of truly general routes to aldehydes themselves. As a result, a great number of relatively specific syntheses have been devised, often relying on partial oxidation or reduction procedures in which the danger of overreaction

Linear and Nonlinear Dispersive Waves,vious difference that a carbanion or carbonium ion source is now required in place of a hydride or proton donor. Favored starting materials are again halocarbons, alkenes, or alkynes, which are readily carbonylated to a range of symmetrical, unsymmetrical, or cyclic ketones. For example, one of the

The last three types of compound can be viewed, respectively, as the products of esterification, amidation, and dehydration of carbamic acids (RNHCOOH), and carbonylative synthes
