The Reactions of 3-Methylcoumarones with Carbonyl Compounds

Condensation Reactions of 2-Aminobenzohydrazide with Various Carbonyl Compounds

Technical iodine was found to catalyze the condensation between 2-aminobenzohydrazide (1) and some aldehydes and ketones in absolute ethanol under mild conditions to afford hydrazone and quinazoline derivatives, respectively. Condensation of 1 with terephthalaldehyde (2) in 1 : 1 molar ratios afforded the hydrazone 3, while hydrazone 4 was formed on using a double molar ratio of 1. On the other...

Reactions of a hydrido(hydrosilylene)ruthenium complex with carbonyl compounds.

Reactions of a neutral silyleneruthenium complex with ketones and aldehydes, and isolation of their agostic intermediates are reported, where an alpha-H abstraction or hydrosilylation of the carbonyl compounds occurs depending on the substituents of the substrates.

Protective effect of phenolic compounds on carbonyl-amine reactions

Role of Titnium Reagents in Carbonyl Compounds Reactions

This article describes some important organic reactions catalyzed by different titanium-reagents. Combinatorial approach and green procedures involving the use of titanium reagents with other transition-metals (such as Sm, Pd, Sn and Zn) in photochemical procedures, and with the auxiliary techniques like microwaves for environmental friendly reaction conditions, are also discussed.

SOLVENT-FREE SYNTHESIS OF PYRROL DERIVATIVES USING MULTICOMPONENT REACTIONS OF 1,3-‎DICARBONYLS, ACTIVATED CARBONYL COMPOUNDS, AND PRIMARY ALKYLAMINES

A one-pot synthesis of pyrrole derivatives via reaction between activated carbonyl compounds, primary amines and 1,3-dicarbonyls under solvent-free conditions is described‎.
