Tris(4-tert-butylphenyl)phosphane, also known as P(t-Bu)3, is a bulky, electron-rich phosphorus-based ligand widely used in organometallic chemistry and homogeneous catalysis. tris(4-tert-butylphenyl)phosphane consists of a central phosphorus atom bonded to three 4-tert-butylphenyl groups, which are phenyl rings with a tert-butyl group (a carbon atom bonded to three methyl groups) attached to the para position. The bulky nature of the ligand provides steric hindrance, which can influence the reactivity and selectivity of metal complexes in various chemical reactions. P(t-Bu)3 is particularly useful in the formation of transition metal catalysts, such as those used in olefin polymerization and cross-coupling reactions, due to its ability to stabilize metal centers and modulate electronic properties.

54409-77-7 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 54409-77-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,4,4,0 and 9 respectively; the second part has 2 digits, 7 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 54409-77:
(7*5)+(6*4)+(5*4)+(4*0)+(3*9)+(2*7)+(1*7)=127
127 % 10 = 7
So 54409-77-7 is a valid CAS Registry Number.

Photochemical transformation of chlorobenzenes and white phosphorus into arylphosphines and phosphonium salts

Gschwind, Ruth M.,Mende, Michael,Scott, Daniel J.,Streitferdt, Verena,Till, Marion,Wolf, Robert

supporting information, p. 1100 - 1103 (2022/02/03)

Chlorobenzenes are important starting materials for the preparation of commercially valuable triarylphosphines and tetraarylphosphonium salts, but their use for the direct arylation of elemental phosphorus has been elusive. Here we describe a simple photochemical route toward such products. UV-LED irradiation (365 nm) of chlorobenzenes, white phosphorus (P4) and the organic superphotoreductant tetrakis(dimethylamino)ethylene (TDAE) affords the desired arylphosphorus compounds in a single reaction step.

Syntheses and Spectroscopic Investigations of Substituted cis- and trans-Dichlorobis(triphenylphospane)platinum(II) Compounds

Brune, Hans Albert,Falck, Manfred,Hemmer, Reinhard,Schmidtberg, Guenter,Alt, Helmut G.

, p. 2791 - 2802 (2007/10/02)

Compounds of the type cis- and trans-dichlorobis(triphenylphosphane)platinum(II) (3) with substituents of different electronic character in the phenyl rings bonded to phosphorus have been synthesized.The coupling constants 1J and the chloro-platinum valence vibrational frequencies are demonstrated to be criteria for unambiguous discrimination between cis- and trans-configurations at platinum; a linear correlation exists between the sum of the ?-constants of the sustituents at the triphenylphosphane and the coupling constants 1J.
