Carbonylation of olefins, alcohols and halides using homogeneous as well as heterogeneous catalysts has been discussed. 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.

Kinetics of hydroformylation of camphene was investigated in the presence of [Rh(CO)(2)(acac)]/P(OPh)(3) catalyst in a temperature range of 363-383 K. The influence of parameters such as stirring speed, camphene, catalyst, ligand concentrations, and partial pressures of H-2 and CO on the activity and selectivity of the catalyst has been studied. The rate showed a first-order dependence with respect to catalyst and camphene concentrations. The effect of partial pressure of hydrogen showed fractional order dependence. The plots of rate versus excess ligand, that is, (P(OPh)(3)) concentration and rate versus CO partial pressure passed through maxima and showed typical substrate/ligand inhibited kinetics. An empirical rate equation has been proposed and found to be in good agreement with the observed rate data. The kinetic parameters and activation energy were also evaluated.

The hydroamination reaction, defined as the direct addition of an N-H bond across unsaturated carbon-carbon bonds, provides a direct route to substituted amines. These amines are indispensable building blocks in nitrogen-containing heterocycles, which are central to pharmaceuticals, agrochemicals, and fine chemicals. Unlike conventional multistep processes, hydroamination enables streamlined and sustainable access to diverse organo-nitrogen frameworks. Within this context, zinc-catalyzed intra- and intermolecular hydroaminations have emerged as particularly attractive due to zinc{\textquoteright}s abundance, low toxicity, wide availability, and its ability to enable efficient catalytic processes with reduced environmental impact. Zinc catalysts operate under mild, environmentally benign conditions, displaying broad substrate compatibility and potential for enantioselective control through coordination with chiral ligands. This review highlights the progress made in zinc-catalyzed hydroamination, encompassing homogeneous and heterogeneous systems, structure-activity relationships, mechanistic insights, and emerging applications. Particular attention is given to the advantages of zinc catalysis in organic synthesis and its relevance to industrial-scale transformations.
