E)-dibenzylideneacetone]palladium(0) complex Pd 2 (dba) 3 . CHCl 3 to form the corresponding isolable complexes [(5a) 2 -(dba)Pd] and [(5b) 2 (dba)Pd]. In agreement with the formation of these complexes, it was found that 5a,b as ligands effectively promote the Suzuki cross-coupling of 4-bromotoluene with benzeneboronic acid. The solid-state structure of bicyclic phosphirane 5b and of the complexes [(5a)(CO) 5
