摘要
The solid condensation of isopropylidene malonate with aromatic aldehydes were carried out by grinding at room temperature or heating at 110～120 ℃ to give 5 arylidene 2,2 dimethyl 1,3 dioxane 4,6 dione . Both conditions afford the condensation high reaction activity. The yield of the product under grinding for 20 min followed by standing for 48 h at room temperature is 56%～80% and that by heating at 110～120 ℃ for 12 min is 55%～74%, respectively.
