14874-99-8 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 14874-99-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,4,8,7 and 4 respectively; the second part has 2 digits, 9 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 14874-99:
(7*1)+(6*4)+(5*8)+(4*7)+(3*4)+(2*9)+(1*9)=138
138 % 10 = 8
So 14874-99-8 is a valid CAS Registry Number.

Synthesis and characterization of [Rh(PP)(PP)]X complexes (PP = DPPE or DPPP, X = Cl? or BF4-). Phosphine exchange and reactivity in transfer hydrogenation conditions

Mannu, Alberto,Vlahopoulou, Gina,Kubis, Christoph,Drexler, Hans-Joachim

supporting information, p. 59 - 64 (2019/02/20)

The synthesis of heteroleptic monomeric cationic Rh(I) bis-diphosphine complex [Rh(dppe)(dppp)]Cl (dppe = 1,2-bis-(diphenylphosphino)ethane and dppp = 1,3-bis-(diphenylphosphino)propane) was achieved by reaction between the neutral dimeric complex [Rhsub

Double hydrophosphination of alkynes promoted by rhodium: The key role of an N-heterocyclic carbene ligand

Di Giuseppe, Andrea,De Luca, Roberto,Castarlenas, Ricardo,Pérez-Torrente, Jesús J.,Crucianelli, Marcello,Oro, Luis A.

supporting information, p. 5554 - 5557 (2016/05/09)

The regioselective double hydrophosphination of alkynes mediated by rhodium catalysts is presented. The distinctive stereoelectronic properties of the NHC ligand prevent the catalyst deactivation by diphosphine coordination thereby allowing for the closing of a productive catalytic cycle.

'Grignard-analogous' rhodium phosphane complexes

Bogdanovic,Leitner,Six,Wilczok,Wittmann

, p. 502 - 504 (2008/10/09)

Interesting stoichiometric and catalytic reactions are possible with the rhodium phosphane complexes [{Ph2P(CH2)(n)PPh2)(n)}2Rh][MgC1] (1: a, n = 2; b, n = 3), which are readily accessible by reaction of the chloride complexes 2 with active magnesium. The 'Grignard-analogous' compounds 1 react to form 3 (E = H, Me SiMe3) by protolysis, alkylation, and silylation. The interconversion of complexes 2a and 1a can be used for catalytic transfer of two electrons from magnesium to CO2 to yield CO and CO3/2+.
