ABSTRACT:
An improved process for producing fluorene compounds of the following formula (II) is disclosed: ##STR1## (wherein R.sub.1, R.sub.2 and R.sub.3 are independently a hydrogen atom, an alkylamino group, a dialkylamino group, a pyrrolidino group or a piperdino group; X and Y are independently a carbon atom or a nitrogen atom; and with the proviso that R.sub.1 and R.sub.2 are not hydrogen atoms simultaneously). The process comprises reacting a lactone compound of the formula (I) (variables being defined as in formula (II) ) ##STR2## with a mixture of an aluminum halide, a carbonyl compound, and a hydroxy bearing compound.
