Reactions of rhenium and manganese carbonyl complexes with 1,8-bis(diphenylphosphino)naphthalene: Ligand chelation, C–H and C–P bond-cleavage reactions

Synthesis of ligands based on naphthalene peri-substituted by Group 15 and 16 elements and their coordination chemistry

“…Addition of the activator Me 3 NO to the reaction mixture of Os 3 (CO) 12 and dppn (1f) resulted in the loss of one PPh 2 group from the ligand and formation of cluster 36 (Scheme 15). 36 is closely related to cluster 24 (see Scheme 11) obtained from the reaction of Ru 3 (CO) 12 with dmpn 1a under similar conditions [32]. Rhenium and manganese carbonyl clusters [Re 2 (CO) 8 …”

“…A range of reactivities was observed, including ligand chelation and C-H and C-P bond-cleavage (Scheme 16) [32]. It is possible that oxygen and chlorine atoms, found crystallographically in some of the products, were introduced at the crystallisation stage.…”

“…A bis(phosphine oxide) complex was isolated from the reaction of [Re 2 (CO) 8 (MeCN) 2 ] with dppn (1f) (Scheme 16) [32]. The dppn bis(phosphine oxide) ligand was incorporated in complex 49 to obtain desirable thermal and electroluminescent properties of the europium species (Scheme 25) [43].…”

“…Reactions of dppn with rhenium and manganese carbonyl clusters [32]. the study was the carbonylation of the metal-carbon bond, which leads to acyl complexes 63 (Scheme 28).…”

Highly efficient electrocatalytic proton-reduction by coordinatively and electronically unsaturated Fe(CO)(κ2-dppn)(κ2-tdt)

“…The diphosphine, 1,8-bis(diphenylphosphino)naphthalene (dppn), has attracted considerable interest as a chelating ligand due to its rigid naphthalene backbone [14][15][16][17][18][19][20][21][22][23][24][25][26]. During our investigations on dithiolate-bridged diiron chelate complexes, we found from the reaction of Fe 2 (CO) 6 (μ-tdt) and dppn, in addition to the expected diiron product Fe 2 (CO) 4 (κ 2 -dppn)(μ-tdt) (1), small amounts of Fe(CO)(κ 2 -dppn)(κ 2 -tdt) (2) were also formed.…”
