[CH2(DDP)2]Br2 (2) and diphosphine (DDP-DDP)Br2 (3) containing a bridging bromine atom. In the course of the reaction of DDP with CF2Br2, two products of sequential substitution of the bromine atoms were isolated, which are 1,4-Br2(DDP) (6) and [CF2(DDP)2]Br2 (7). Tris(pentafluorophenyl)phosphine reacts with DDP at the C—F bond with the formation of 1,1-addition product 8. Compounds 2, 3, 7, and 8 contain

been formed in this reaction. The reaction in the 3a,6a-diaza-1,4-diphosphapentalene–[Ph3PC≡CPh]Br–carbazole three-component system proceeds as addition of carbazole to the initially formed complex of 3a,6a-diaza-1,4-diphosphapentalene with [Ph3PC≡CPh]Br with the rupture of the P–N bond. The products and intermediates of the reaction have been simulated by B3LYP/6-31+G(d) method.
