Abstract: A novel cyclic 1,3-diphospha-butane was obtained starting from 9-trimethylsilyl-fluorene and PCl3 in a one-pot procedure and investigated through spectroscopic methods. Theoretical studies were also carried out, showing that the head-to-tail isomer of 1, 3-diphosphacyclo-butane is more likely to be formed during the reaction through the dimerization of a fluorenyl-substituted phopsphaalkene. This type of cyclic derivative can replace phosphaallenes as ligands in the synthesis of coordination compounds with potential biological activity. Keywords: phosphaalkenes, diphosphacyclo-butane, DFT calculations |
