5-Phenyl-1,2,3,4,6,7,8,9-octahydrodibenzophosphole (L) has been synthesized by reacting DBU with the PhPBr2-1,1′-bicyclohexenyl cycloadduct. Its chemical properties have been compared with those of more classical phospholes. Its P-oxide and P-sulfide are monomeric. A double ring-expansion reaction is observed with benzoyl chloride as with simple phospholes. On the contrary we met a limited success with the P—Ph bond cleavage by K in THF and we did not succeed at all when attempting a P—Ph → P—tBu exchange by reaction with tBuLi. The corresponding phosphacymantrene has been obtained with Mn2(CO)10. σLFe(CO)4, σ,ηLFe2(CO)7 ans ηLOFe(CO)3 complexes have been obtained from the reactions of L or its P-oxide with Fe3(CO)12.
