Carbon monoxide displacement

The dicarbonyl species thus produced undergo photolytically promoted carbon monoxide displacement by phosphine to give racemic mixtures of chiral a,/ -unsaturated iron-acyl complexes35. 

Carbon monoxide displacement from M(CO)j similarly gives RjGeMICO), for M = Cr, W. The RjGeM products contain 3-coordinate Ge. 

The parent group, HNO, was detected in the complex [OsCl2(HNO) (CO)(PPhj)2] formed through protonation of the coordinated nitrosyl group in [OsCl(NO)(CO)(PPh3)2] using hydrogen chloride. Carbon monoxide displaced HNO, but in solution the complex disproportionated with loss of HCl (243).

A new platinum(O) carbonyl complex has been prepared by the reaction of 3 equiv. of carbon monoxide with a carbene complex (Equation (1)). Not only does the carbon monoxide displace an existing ligand but coordinated GO is also attacked by the ligating nitrogens, with the siloxy group migrating to give the unusual tris-carbene carbonyl complex 1, where all the donor atoms are carbon. Yields are reported to be quantitative, and an X-ray structure has a short Pt-GO bond of 1.868(6) A with a GO stretch of 2,038 cm Further aspects of the synthesis of both 1 and its precursor are discussed in Sections 8.07.3.2.2 and 8.07.3.3. 

As can be seen, the chemical equations indicate that these reactions could often be considered as carbon monoxide displacement reactions. The condensations involving the square-based pyramidal dianion [Fe5C(CO)i4] and some neutral species with labile ligands shown in the scheme in Fig. 2.43 may be cataloged into the same type of reactions. The same is valid in the desplacement of the chlorine atom in the chloromethyl derivative Co3(CO)9CCl by mononuclear and cluster carbonyl metallates according to the following equations.

Carbon Monoxide (CO) Carbon monoxide is formed during the ineomplete combustion of fossil fuels (petroleum, natural gas, and coal). It is emitted mainly by motor vehicles. In humans and other animals, carbon monoxide displaces oxygen in the blood, forcing the heart and lungs to work harder. At high levels, CO can cause sensory impairment, decreased thinking ability, unconsciousness, and even death.
