Rh(NBD)(dppe)+ (NBD=norbornadiene, dppe=1,2-bis(diphenylphosphino)ethane) intercalated in hectorite, a swelling layered silicate, catalyzes the overall 1,2 and 1,4 addition of hydrogen to 1,3-butadiene, isoprene,and 2,3-dimethyl-1,3-butadiene at rates which range from -5 to 0.83, relative to the homogeneous catalyst.The yields of 1,2 addition products are 1.5 to 2.3 times higher than those obtained under homogeneous reaction conditions.The intercalation effects depend in part on the extent to which the silicate interlayers are swelled by solvent.

Complexes formed by adding Group Vb ligands to ClO4 in the presence of potassium hydroxide catalyze hydrogen transfer from isopropanol to acetophenone, cyclohexene and other unsaturated substrates.The catalytic activity depends upon the nature of the mono- or bidentate nitrogen- or phosphorus-donor ligands. 2>ClO4 catalyses the selective reduction of hexyne or diolefins.
