Abstract: A number of BF2-chleate compounds were developed based on 4,6-dichloropyrimidine. The electron withdrawing ability of the -BF2 group markedly enhances the reactivity of the chlorides within chloropyrimidine. Consequently the BF2-chelate compounds can be modified in a variety of ways by nucleophilic substitutions. The compounds prepared in this work consist of 4,6-dichloropyrimidine and BF2-chelate moieties separated by methylene chains of tunable lengths. Such a versatile series of compounds may provide an opportunity to study the intramolecular energy transfer processes with respect to the donor-acceptor distances. Also it is suggested that the present BF2-chelate compounds will be useful for developing various types of energy/electron transfer systems and fluorescent materials.
