The use of ethylene glycol as additive in the N -oxide-promoted intermolecular Pauson-Khand reaction (PKR) has been studied. The addition of 15% ethylene glycol to the reaction mixture consistently increased (from 20% up to 2-4-fold) the reaction yields.
Linking two alkyne-bridged dicobalt complexes via a urea-based ligand: Synthesis and spectroscopic and structural characterization of {[Co2(CO)6(μ-HC≡C-)]-CH2nh} 2C=O

Treatment of Co2(CO)8 with HC≡CCH2NH2 under mild reaction conditions yielded an unusual complex of {[Co2(CO)6 (μ-HC≡C-)]-CH2NH}2C=O, 1. The structure of 1 was established by X-ray diffraction analysis. The compound 1 can be viewed as two propargylamine-bridged dicobalt complexes coupled by a carbonyl group. Obviously, carbonylation of a primary amine took place during this reaction.
