CO Surrogates: A Green Alternative in Palladium-Catalyzed CO Gas Free Carbonylation Reactions

Current organic chemistry, 2020
Carbonylation reactions with carbon monoxide (CO) provide efficient and attractive routes for the synthesis of bulk and fine chemicals. However, the practice of using a large excess of an inflammable, lethal and greenhouse CO gas is always a concern in

Binuclear Cyclopentadienylcobalt Carbonyls:  Comparison with Binuclear Iron Carbonyls

Journal of the American Chemical Society, 2005
The binuclear cyclopentadienylcobalt carbonyls Cp2Co2(CO)n (n = 3, 2, 1; Cp = eta5-C5H5) are studied by density functional theory using the B3LYP and BP86 functionals. The experimentally known monobridged isomer Cp2Co2(CO)2(mu-CO) and the tribridged isomer Cp2Co2(mu-CO)3 of Cp2Co2(CO)3 with formal Co-Co single bonds are found to be similar in energy ...

Darmstadtium carbonyl and carbide resemble platinum carbonyl and carbide

Chem. Commun., 2004
DsC and DsCO are calculated to be very similar to PtC and PtCO, suggesting that even the latest 6d elements resemble the corresponding 5d elements chemically.

Alkylcobalt carbonyls. 8. (Chloromethyl)- and (chloroacetyl)cobalt carbonyls

Organometallics, 1987
ClCH2C(O)Co(CO)4 (I) is prepd. by the reaction of ClCH2COCl with Na[Co(CO)4]. I readily decarbonylates to ClCH2Co(CO)4 (II). I is formed from II at .apprx.5 bar of CO pressure and room temp. or at 1 bar of CO by cooling to .apprx.-10 Deg in a reversible reaction.
