Yield:-

Reaction Conditions:

with Iodine monochloride

Steps:

IV EXAMPLE IV
EXAMPLE IV Iodine monochloride (10 g) was dissolved in 30 ml of TMP with cooling. Considerable heat evolved. This solution was added dropwise to a solution of 5 g of fluorene in 30 ml TMP stirred, held at 83°-100° C overnight (about 12 hours), refrigerated (at 5° C for about 6 hours) and filtered to give 4.8 g of white, fine needles. Another 2.4 g was recovered from filtrate - total crude yield 60%. Recrystallized from tetrahydrofuran to which a few (2) ml of ethyl alcohol was added 2,7-Diiodofluorene was obtained: 5.6 g, 44% of white needles, mp 214°-215°, reported (in F. Dewhurst, P. K. J. Shah, J. Chem. Soc., 1503 (1969)) mp 214° C.
