ABSTRACT:
Disclosed is a novel acid halide derivative represented by Formula (I):wherein X and Y may be the same or different and are each a halogen atom; and R is a lower alkyl group. By cyclizing the acid halide derivative of Formula (I) in the presence of a catalyst, an indanonecarboxylic acid ester represented by Formula (VI):wherein X and R are as defined above, is produced. Such indanonecarboxylic acid esters are useful as intermediates for insecticides.
