2,2,6,6-Tetramethylheptane-3,5-dione was synthesized using pinacolone,methyl pivalate as starting material and sodium hydride as base in tetrahydrofuran.

The results show that:the optimum hydrogen-grabbing agent and reducing agent for the alkylation and selective reduction of keto-carbonyl are sodium hydride .

Sodium hydride was prepared by means of catalytic synthesis and direct synthesis.
