โœฆ Synopsis

Homogeneous Hydrogenation of Alkynes and Dienes a) [Cr(CO) 3 (mbz)] = [Cr(CO) 3 (methyl benzoate)] (1 a). Reaction conditions: solvent acetone, reaction temp. 120 8C, substrate : catalyst ratio = 5 : 1. b) [Cr(CO) 3 (nap)] = [Cr(CO) 3 (naphthalene)] (1 b). Reaction conditions: solvent THF, reaction temp. 45 8C, substrate : catalyst ratio = 5 : 1. c) Determined by GC analysis relative to internal standard. 14 Homogeneous Hydrogenation of Alkynes and Dienes 378 Scheme 14.1 Proposed mechanism for the hydrogenation of phenyl acetylene catalyzed by [(PP 3 )FeH(H 2 )] + BPh 4 -(3); the anion is BPh 4 -throughout in this scheme.

Chemical modification of polymers via catalysis is of great importance as it provides an efficient synthetic route for the production of novel polymers with desirable physical properties. It also allows the introduction of functional groups that are often inaccessible by conventional polymerization
