A highlyefficient and practical method for the synthesis of propargylic substituted 1,3-dicarbonyl compounds with direct use of propargylic alcohols in the presence of inexpensive and environmentally benign FeCl3 (5 mol%) has been presented. The reaction works with varieties of substrates at room temperature without an inert atmosphere with an excellent yield. The present method can also be employed
