Application of 32993-05-8. Chemistry is an experimental science, and the best way to enjoy it and learn about it is performing experiments.Introducing a new discovery about 32993-05-8, Name is Chlorocyclopentadienylbis(triphenylphosphine)ruthenium(II)
The syntheses of cationic ruthenium(II) allenylidene complexes [(1a-e)PF6] of the type [CpRu(=C=C=CR2)(PPh3)2]PF6 (1a, R2C: = cycloheptatrienylidene; 1b, R2C: = 2,7-dimethyl4,5-benzocycloheptatrienylidene; 1c, R2C: = 2,7-diphenyl-4,5-benzocycloheptatrienylidene; 1d, R2C: = dibenzo[a,e]cycloheptatrienylidene; 1e, R2C: = 4,5-dihydrodibenzo[a,e]cycloheptatrienylidene) are reported. In the series 1a-e, the decreasing ability of R2C: to stabilize a positive charge results in a tuning of the electronic and optical properties by changing the relative contributions of the two canonical forms [Ru+]=C=C=CR2 (A) and [Ru]-C=C-CR2+ (B), which is studied particularly by NMR and UV/visible spectroscopy. The first molecular hyperpolarizabilitiy beta of (1b)PF6 has been determined by hyper Raleigh scattering. The X-ray crystal structures of (1b)PF6, (1d)PF6·CH2Cl2, and the acetylide complex CpRu(C=C-C7H7-2,4,6)(PPh3)2 are presented.
