A convenient, highlyefficient and green approach for synthesis of tetraketones from aromaticaldehydes with dimedone and 1,3‐indanedione at room temperature in PEG‐400 is described. The use of PEG‐400 as the reaction medium and avoiding the use of any catalyst makes the process environmentally benign. Seven new compounds are reported.
