Highlights of contributions on the activity, selectivity and stability of catalysts for carbonylation reactions are discussed. Kinetics and mechanism including characterization of the intermediate catalytic species has also been reviewed. The performance of anchored Pd complexes on mesoporous supports (MCM-41 and MCM-48), water soluble Pd complexes and supported Pd catalysts in carbonylation of aryl alcohols and olefins has been discussed in the context of catalyst-product separation. Some aspects of kinetic modelling and reaction engineering of these multiphase catalytic reactions have also been reviewed.</p>10aCarbonylation10acatalysis10aHeterogenization10ahomogeneous10aPalladium1 aSarkar, B., R.1 aChaudhari, Raghunath, V.  uhttps://library.ncl.res.in/content/carbonylation-alkynes-alkenes-and-alcohols-using-metal-complex-catalysts-002098nas a2200253   4500008004100000022001400041245010300055210006900158260010600227300001200333490000700345520115900352653001001511653001401521653001301535653002501548653002201573653002501595653002501620100001601645700002401661700002901685856013001714       2010                        eng d  a0009-250900aKinetics of reductive alkylations of phenylenediamines: influence of substrates isomeric structure0 aKinetics of reductive alkylations of phenylenediamines influence  aTHE BOULEVARD, LANGFORD LANE, KIDLINGTON, OXFORD OX5 1GB, ENGLANDbPERGAMON-ELSEVIER SCIENCE LTDcJAN  a232-2390 v653 a<p>Reductive alkylation of ortho-, meta- and para-phenylenediamines (PDAs) with methyl ethyl ketone (MEK) has been studied in a semi-batch slurry reactor in the presence of a commercial 3% Pt/Al(2)O(3) catalyst. It was observed that the PDA isomers differ remarkably from each other in their activity in reductive alkylation and product distribution. The activity was found to decrease in the following order: PPDA &gt; OPDA &gt; MPDA. To understand the substrate structure-activity correlation, the homogeneous equilibrium reactions involved in the alkylation step and the overall catalytic reactions were studied separately. Kinetics of reductive alkylation of PDAs with MEK as a solvent and alkylating agent with 3% Pt/Al(2)O(3) catalyst was studied in a semi-batch slurry reactor over a temperature range of 373-453K and pressure range of 2.07-6.21 MPa. Semi-batch slurry reactor models were developed and kinetic parameters were estimated by fitting the integral batch reactor data at different temperatures to understand the influence of different reaction steps on the activity and selectivity of different products.
