CHF 2 Cl has been converted to CHF 3 and CH 4 as main products when hydrogenolyzed in the presence of RhCl 3 (py) 3 and other homogeneous catalysts modified with bases (amines and fluoride ion). Pyridine additive was partly hydrogenated and then alky

2‐Aza‐1,3‐butadienes have been synthesized from carbonyl compounds and 1,1,1,3,3,3‐hexamethyl‐disilazane in the presence of cobalt‐containing catalysts. The best yields (up to 95%) were achieved in the case of aldehydes branched in the α

Silylcobalt tetracarbonyls were reacted with various amines (B) in non-polar solvents to form silylammonium tetracarbonylcobaltate contact ion pairs formulated as [BSiR3+, −Co(CO)4]. The compounds were characterized by IR and multinuclear magnetic

Rhodium and palladium complexes proved to be effective catalysts in hydrodechlorination of CFC and HCFC compounds in homogeneous phase. RhCl 3 (py) 3 and in situ generated Pd(P i Pr 3 ) 3 surpassed Pd/Al 2 O 3 , the most active heterogeneous catalyst

A polar type liquid having a secondary alcohol substituent on a branched alkane skeleton, SOH, was used as stationary phase. The molecules of this stationary phase are nearly isomorphous and isochor with those of the branched alkane, C 78 , elected a

‘Early–late’ bimetallic complexes of the type [(acac) 3 M–OCCo 3 (CO) 9 ] (M=Zr ( 1 ), Hf ( 2 )) are formed in reactions between (acac) 3 MCl and NaCo(CO) 4 . These complexes exhibit a remarkable stability. They were characterized by their IR

[η 3 -η 5 -(Silyloxy–alkenyl)]-cobalt carbonyls and various silyl ethers were formed in the cobalt carbonyl mediated silylations of α,β-unsaturated and aromatic carbonyl compounds. A silyloxonium tetracarbonylcobaltate tight ion pair was sugges

The rate of acetylcobalt tetracarbonyl methanolysis between 40 and 60 °C is first-order with respect to the acetylcobalt tetracarbonyl concentration and independent of the carbon monoxide concentration. The reaction is susceptible to both acid and b

The hydrosilylation of carbon monoxide with cobalt carbonyls under relatively mild conditions resulted in a Fischer-Tropsch-analogous reductive coupling of CO. Alkyl silyl ethers, 1,2-bis(silyloxy)-1-alkenes and higher molecular weight compounds with
