A convenient esterification reaction of poly(methacry1ic acid) (PMAA) with certain alkyl halides was performed using 1,8-diazabicyclo-[5.4.0] -7-undecene (DBU) as a base in aqueous solution or in water. The esterification reaction of PMAA with propargyl bromide (PB) proceeded very smoothly and quant

The reactions of alkali metal salts of anthracene with alkyl halides result in the formation of 9,10-dialkyl 9,10-dihydroanthracenes as the principal product, although appreciable quantities of other adducts, notably the 1,2-and 1,4-dialkyl compounds, are also formed. When the disodium salt is used
## Abstract The activation energy parameters for the reaction of PdX (X=Cl^β^, Br^β^) in aqueous halide acid solution with thiourea (tu) and selenourea (seu) have been determined. High rates of reaction parallel low enthalpies and appreciable negative entropy of activation. The rate law in each cas
## The rates and activation energy parameters of halide ligand substitution in PdXf (X = Cl-, Br-), with N-alkyl substituted thioureas in aqueous halo acid solutions have been determined for the first kinetically distinguishable step. Ligand and product composition is substantiated by analytical dat
