The study focuses on the synthesis and characterization of neopentyl esters of acrylic and methacrylic acids. Neopentyl alcohol, a key reactant, was prepared using two methods: the Whitmore method involving tert-butylmagnesium chloride and pivalyl chloride, and the more practical lithium aluminum hydride reduction of pivalic acid. Neopentyl acrylate was synthesized from neopentyl alcohol and either acryloyl chloride or acrylic acid, while neopentyl methacrylate was prepared from neopentyl alcohol and either methacryloyl chloride or methacrylic acid. The esters' physical properties were measured and reported. The study also highlighted the partly hindered character of neopentyl methacrylate, which affected its saponification process.

The research focuses on the nickel-catalyzed hydrodehalogenation of aryl and alkyl halides using iso-propyl zinc bromide or tert-butylmagnesium chloride as reagents. The purpose of this study is to develop an efficient and selective method for the transformation of carbon-halogen bonds into carbon-hydrogen bonds, which is crucial for organic synthesis and industry, particularly for the conversion of chlorinated arenes due to their negative environmental and health impacts. The researchers used a straightforward nickel complex as a pre-catalyst, achieving good to excellent yields and chemoselectivities for a variety of aryl and alkyl halides. The study concluded that a well-defined nickel complex, specifically complex 6, could effectively convert a range of aryl and alkyl halides under mild reaction conditions. Future work is planned to deepen the understanding of the reaction mechanism.
