Chromium hexacarbonyl synthesis essay - …
Molybdenum hexacarbonyl is widely used in technique - it is easily vaporized and decomposed bythe electron beam providing a convenient source of molybdenumatoms.Mo(CO)6 is also a popular reagent in organometallicsynthesis becauseone or more CO ligands can be displaced by other donor ligands. Forexample, Mo(CO)6 reacts with to affordMo(CO)4(bipy). UV-photolysis of a solution ofMo(CO)6 gives Mo(CO)5(THF). Many metalcarbonyls are similarly photo-activatable.

Iranpoor, N.; Firouzabadi, H.; Davan, E. E.; Nematollahi, A.; Firouzi, H, R. A novel nickel-catalyzed synthesis of thioesters, esters and amides from aryl iodides in the presence of chromium hexacarbonyl. New J. Chem. 2015, 39 (8), 6445-6452.
Recently, we have developed several synthetic routes to a series of chalcogen-containing group 6 (emphasizing on chromium) carbonyl clusters, in which the interesting structural transformations, reactivity, and properties of the resultant clusters have also been investigated. This review will focus on the aspects of the research carried out in our laboratory. In this account, the practical synthetic methodologies and metal-metal exchange and cluster expansion reactions together with structural features of these Cr-containing complexes are systematically described and compared.
Preparation of chromium hexacarbonyl from chromium metal ..
Molybdenum hexacarbonyl (also calledmolybdenum carbonyl) is the with the formula Mo(CO)6. This colorlesssolid, like its and analogues, is noteworthyas a volatile, air-stable derivative of a metal in its zerooxidation state.
Mo(CO)6 adopts an consisting of six rod-like CO radiating from the central Mo atom. Arecurring minor debate in some chemical circles concerns thedefinition of an "" compound. Usually,organometallic indicates the presence of a metal directly bondedvia a M-C bond to an organic fragment, which must in turn have aC-H bond. By this strict definition, Mo(CO)6 is notorganometallic.

Mo(CO)6 is prepared by the of molybdenum chlorides or oxides undera pressure of , although it would beunusual to prepare this inexpensive compound in the laboratory. Thecompound is somewhat air-stable and sparingly soluble in nonpolarorganic solvents.
Process for the preparation of chromium hexacarbonyl
The preparation of thioesters through the iron-catalyzed coupling reaction of thiols with aldehydes is described. The reactions were carried out by using -butyl hydroperoxide (TBHP) as an oxidant and water as a solvent in most cases. This system is compatible with a variety of functional groups.
CHROMIUM HEXACARBONYL ISOMERIZATION OF ..
Hexacarbonylchromium is widely used as a catalyst for isomerization of alkenes. It is involved in the hydrogenation of 1,3-conjugated dienes and oxidation of allylic and benzylic positions. It acts as a precursor to prepare phenanthrenes, tricarbonyl(arene)chromium and Fischer carbine complexes.
