A nucleophile is any negative ion or neutral molecule whose electronic configuration consists of at least one unpaired electron pair. In chemical reactions, the nucleophile attacks the positive center of some other molecule or positive ion, and then...

In chemistry, a nucleophile (literally nucleus lover as in nucleus and phile) is a reagent that forms a chemical bond to its reaction partner (the electrophile) by donating both bonding electrons.[1] Because nucleophiles donate electrons, they are by...

INTRODUCTION Transesterification as a cure chemistry for coatings is well-documented in the literature.[1-4] Fairly weak transesterification catalysts, such as zinc octoate, are generally used in transesterification cure with activated ester or hydroxyl functional materials. The more effective strong base transesterification catalysts, such...

Syntheses of methyl[1,2,4 ]triazolo- or methyltetrazolopyridazine isomers, their separation and nucleophilic substitution with morpholine, dimethylamine and hydrazine have been described. The lipophilicity of the azolopyridazines has been measured and related to the number and sites of the methyl substituents. The structures of new methylated...
