Arylidene thiazolineone derivatives are synthesized by solid state condensation of aromatic aldehydes with 2,4 thiazolidinedione or N phenylrhodanine in the presence of NaAc at 120~140 ℃ for 10 min with yields of 55...
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 condit...
