During the syntheses of fluorene derivatives, we have obtained by the following reactions two kinds of rotational isomers which are stable at room temperature in solution. Compound (A) mp 293'C(dec) was first obtained by Pinck and Hllbert 1) on the Michael reaction of 9,9'-blfluorenylidene (1) with
