This chapter focuses on organometallic chemistry that is stated to be the most rapidly expanding of all the branches of chemistry. Organometallic compounds are classified according to carbon–metal bond type into four principal categories: (a) ionic, (b) covalent, (c) electrondeficient, and (d) : C.B. Milne, A.N. Wright. The Nature Index tracks the affiliations of high-quality scientific articles. Updated monthly, the Nature Index presents research outputs by institution and country. Use the Nature Index to interrogate publication patterns and to benchmark research performance. Nickel(II) acetylacetonate ( mol%) in combination with sodium iodide (2 equiv.) and potassium carbonate ( equiv.) was identified as the optimal catalytic system for the current transformations.

A variety of secondary alcohols, 1,2-diols and primary alcohols were selectively oxidized in excellent yields to their corresponding ketones, 1,2-diketones and aldehydes with aqueous 30% hydrogen.

For instance, aro- matic amines are much weaker bases. This reduced basicity can be explained on the basis of the resonance of the lone pair of electrons on the nitrogen atoms with the electrons of the aromatic ring system (P. Sykes, "A Guide Book to Mechanism in Organic Chemistry", Longmans, London, , p. 52): o : A.K. Sarkar.

Afterword, the Ca-PCT sample was eluted with a solution of humic acids (HA) in a chromatography column (HA solution concentration = mg L-1, pH = , flow rate = mL h-1). HA are natural organic polymers containing aromatic blocks and are produced by the biological decomposition of organic matter from plants and other organisms. It catalyses direct aldols in water with high de and ee, as do several of its silyloxy analogues The first asymmetric direct aldol of 1,2-diketones and ketones, to give 2-hydroxy1,4-diketones, has been reported l-Proline derivatives give high regio-, diastereo-, and enantio-selectivity in the reaction of 1-arylpropane-1,2-diones with.   Pericyclic Reactions: FMO Approach-Abstract of Issue M.
