Tetrahydrofuran → 1,1-Diethoxy-2-methylprop-1-ene

Participants

Reaction Steps

To a solution of the compound of preparation 41(b) (2.3 g, 0.02 mol) in THF (50 mL) was added potassium t-butoxide (2.3 g, 0.02 mol). The mixture was stirred at room temperature for 1 hour, then hexane (20 mL) was added. The mixture was filtered through celite, the filtrate was concentrated in vacuo, and the residue was distilled at 50 mmHg to afford 2.1 g of 1,1-diethoxy-2,2-dimethylethylene (Formula V: R3 =R4 =CH3 ; R5 =R6 =OC2H5).
