Abstract:	The complex [PdCl₂(NH₂(CH₂)₁₂CH₃)₂] has been heterogenized on two different activated carbons and tested as a catalyst for the semihydrogenation of 1-heptyne. The results are compared with those previously reported with the -Al₂O₃-supported complex. An important effect of the support porosity has been found. The location of the complex in the narrow pores induces shape selectivity. The effect of the support in concentrating the substrate close to the active species has been observed. A very active and selective catalyst has been prepared using an essentially microporous carbon.

Keywords:	1-heptyne hydrogenation metal complexes heterogeneous catalysis activated carbon
