(Z)-3-Methylideneselenophthalides 5A and (Z)-3-methylidenetellurophthalides 5B were easily prepared by the regioselective and stereoselective reaction of 2-ethynylbenzoyl chlorides 3 with sodium hydroselenide and sodium hydrotelluride in good yields, resp

2-Alkynylbenzoyl cyanides react with carboxylic acids via a cyclic allene intermediate to produce 2-acylamino-3-acylindenones in good yield. The high reactivity of the 2-acylamino moiety of the product for a substitution reaction can be utilized for the s
