Deprotonation and subsequent alkylation of phosphine-metal carbonyl complexes

Isolation of the first Li/halogen phosphinidenoid transition-metal complex

“…This finding is in line with the comparable cases of [(OC) 5 M(PPh 2 H)] and [(OC) 5 M(PPh 2 Li)] (M = Cr, Mo, W). 16 According to the calculated 31 P and 19 F NMR chemical shifts 17 (gas phase) of model complexes III-2a(Me) (d( 31 P)…”

1,5,9-Triphosphacyclododecane complexes of molybdenum and tungsten; crystal structure of tricarbonyl[1,5,9-tris(isopropyl)-1,5,9-triphosphacyclododecane]-molybdenum(0)

“…[2.577(2) A where R3 = Ph,] The average cis-P-Mo-P angles are greater than the idealised 90" and vary over a wide range from 92.52 (5) (for R, = MePh,) to 104.62( 7)" (for R3 = Ph,). In our examplethere are some obvious constraints on the metal-ligand bonding imposed by the macrocycle 'backbone'.…”

Syntheses and reactivity of molybdenum complexes containing the diphenylphosphinodithioformato ligand

“…Abstraction of a proton from the metal coordinated phosphine has been reported for the synthesis of the phosphorus derivatives [4]. Interestingly, up to now, only a few examples are known for dialkylphosphinodithioformato ligand, R 2 PCS 2 − .…”
