Studies of activity and stereospecificity in polymerizations of propylene and butene-I with several metal-complex catalysts fixed on a graphite surface are reported. High catalytic activity was observed at a strictly determined Ti:graphite ratio. Maximum stereospecificity is observed at the maximum

## Hydroformylation of Olefins in the Presence of Rhodium Catalysts Immobilized on Polymeric Pyrrolidinopyridines. -The hydroformylation of olefins in the presence of catalytic systems based on RhCl3 and polymeric pyrrolidinopyridine is studied. This thermostable catalyst system is shown to be mo
The Cu-Na-HSZ-320 zeolite can be utilised as an efficient and reusable catalyst in the allylic oxidation of olefins with tert-butyl perbenzoate to give the corresponding allylic esters in good yield and excellent selectivity.
Effective cross-metathesis of H 2 C C(H)SiR 3 , where SiR 3 =Si(OMe) 3 , Si(OEt) 3 , Si(OSiMe 3 ) 3 , with selected olefins in the presence of (PCy 3 ) 2 Cl 2 Ru( CHPh) (I) is described. Treatment of p-substituted styrenes, 1-alkenes and selected allyl derivatives H 2 C CHCH 2 R% (R%=SiMe 3 , Si(OEt
