General Description

2H-Pyran, tetrahydro-2-[4-(trifluoromethyl)phenoxy]-, also known as flucythrinate, is a synthetic pyrethroid insecticide commonly used in agriculture to control a wide range of pests. It is highly effective against a variety of insects, including caterpillars, beetles, aphids, and leafhoppers. Flucythrinate works by disrupting the nervous system of insects, leading to paralysis and eventual death. It is used on a variety of crops, including fruits, vegetables, and grains, and is considered to have low to moderate toxicity to mammals. However, it has been found to be highly toxic to aquatic organisms and bees, and caution must be taken to minimize environmental impact when using this chemical.

2-Substituted 4-(trifluoromethyl)phenols by directed ortho-lithiation

A broad variety of 2-substituted 4-(trifluoromethyl)phenols can be prepared in a large scale by o-lithiation and reaction with electrophiles in good to excellent yields. The key for the selectivity is the superior ortho-directing effect of the THP-protect

Ru-based complexes as heterogeneous potential catalysts for the amidation of aldehydes and nitriles in neat water

Five novel heterogeneous mononuclear complex-anchored Ru(III) have been efficiently sono-synthesized and characterized by utilizing several analytical techniques. The assembled complexes could be utilized as effective, robust and recyclable (up to eight consecutive runs) catalysts for one-pot transformation of a vast array of nitriles and aldehydes to primary amides in H2O under aerobic conditions. Moreover, some unreported di- and tetra-amide derivatives were obtained also under the optimal conditions. The results of ICP/OES analysis demonstrated that there is no detected leaching of the recycled catalyst, which suggests the real heterogeneity of the present protocol. The present Ru-complexes exhibited superiority compared to other reported catalysts for amide preparation in terms of low catalyst load, short reaction time, low operating temperature, no hazardous additives required, and high values of TON (990) and TOF (1980 h11).
