چکیده

The reaction of alkaline 2,4-dihydroxyquinoline 1 and 1-tetralone 2 in 2% sodium hydrox­ ide solution with vinyl acetate afforded a brown solid 3, which on treatment with phospho­ rous oxychloride yielded 2,4-dichloro-3-[l’-(l-chloro-naphth-2-yl)ethyl]quinoline (4). The same reaction of 1 and chromanone 7 with vinyl acetate afforded 2,4-dichloro-3-[l’-(4-chloro2-methyl-chromen-3-yl)ethyl]quinoline (9).

A Convenient Synthetic Protocol to 1,2-Bis(dialkylphosphino)ethanes

1,2-Bis(dialkylphosphino)ethanes are readily prepared from the parent phosphine oxides, via a novel sodium aluminium hydride/sodium hydride reduction protocol of intermediate chlorophosphonium chlorides. This approach is amenable to multi-gram syntheses, utilises readily available and inexpensive reagents, and benefits from a facile non-aqueous work-up in the final reductive step.

Abiotic degradation of chlorinated ethanes and ethenes in water

INTRODUCTION Chlorinated ethanes and ethenes are among the most frequently detected organic pollutants of water. Their physicochemical properties are such that they can contaminate aquifers for decades. In favourable conditions, they can undergo degradation. In anaerobic conditions, chlorinated solvents can undergo reductive dechlorination. DEGRADATION PATHWAYS Abiotic dechlorination is usual...

Ligand substitution reactions of a phenolic quinolyl hydrazone; oxidovanadium (IV) complexes

BACKGROUND Quinoline ring has therapeutic and biological activities. Quinolyl hydrazones constitute a class of excellent chelating agents. Recently, the physiological and biological activities of quinolyl hydrazones arise from their tendency to form metal chelates with transition metal ions. In this context, we have aimed to study the competency effect of a phenolic quinolyl hydrazone (H2L; pri...
