Reaction Steps

Dry hydrogen chloride is passed into a solution of 2,7-dibromo-9H-fluorene-9-carbonitrile [obtainable e.g. from the corresponding 2,7-dibromo-9H-fluorene carboxaldehyde (J. Org. Chem., 1944, 9, 155) by oximation and dehydration] by a process analogous to that described in Example 1(a). After working up by a procedure similar to that described in Example 1(a) the product can be used crude or purified before use in Example 2(b) below.
