Description

1,2-Bis(di-tert-butylphosphino)ethane, commonly known as dtbpe or BPE, is a bidentate ligand characterized by its central ethane backbone with two di-tert-butylphosphino (dtbpe) groups attached to the terminal carbon atoms. The bulky and electron-rich phosphine groups of BPE offer steric and electronic protection to metal centers, which is instrumental in stabilizing and activating a diverse array of metal complexes. Its versatile coordination properties and unique steric effects render BPE an indispensable tool in the advancement of various catalytic processes.

Check Digit Verification of cas no

The CAS Registry Mumber 107783-62-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,7,7,8 and 3 respectively; the second part has 2 digits, 6 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 107783-62:
(8*1)+(7*0)+(6*7)+(5*7)+(4*8)+(3*3)+(2*6)+(1*2)=140
140 % 10 = 0
So 107783-62-0 is a valid CAS Registry Number.

A convenient synthetic protocol to 1,2-bis(dialkylphosphino)-ethanes

Doyle, Laurence R.,Heath, Alex,Low, Choon Heng,Ashley, Andrew E.

, p. 603 - 608 (2014)

1,2-Bis(dialkylphosphino)ethanes are readily prepared from the parent phosphine oxides, via a novel sodium aluminium hydride/sodium hydride reduction protocol of intermediate chlorophosphonium chlorides. This approach is amenable to multi-gram syntheses, utilises readily available and inexpensive reagents, and benefits from a facile non-aqueous work-up in the final reductive step.

Ni(cdt) reacts with tBu2PC2H4PtBu2 in pentane at 20 deg C to yield brownish crystals of (tBu2PC2H4PtBu2)Ni(η2-C12H18) (1).The molecular structure of 1, as established by X-ray crystallography, exhibits a trigonal-planar coordination geometry of the nickel center with a η2-bonded cdt ligand.In the crystal 1 exists as two enantiomers, which are determined by the left- or right-handed screw axis of the cdt ligand.The cdt ligand in 1 resists most typical displacement reactions but 1 reacts with CO at -78 deg C to afford the colorless 18e complex (tBu2PC2H4PtBu2)Ni(CO)2 (2).From the reaction of Ni(cod)2 with tBu2PC2H4PtBu2 yellow needles of (tBu2PC2H4PtBu2)Ni(η2-cod) (3) are obtained.Low temperature NMR spectroscopy established that only one diene C=C bond is coordinated to nickel(0).At higher temperatures a rapid exchange of the coordinated and unbound C=C bonds is induced.When solutions of 3 are kept at 20 deg C for several days the dinuclear, almost insoluble yellow complex tBu2PC2H4PtBu2)Ni>2(μ-η2,η2-cod) (4) precipitates.The reaction of Ni(C2H4)3 and tBu2PC2H4PtBu2 affords orange (tBu2PC2H4PtBu2)Ni(C2H4) (5).From Ni(1,5-hexadiene)2 and tBu2PC2H4PtBu2 in 1,5-hexadiene the yellow-greenish complex (tBu2PC2H4PtBu2)Ni(η2-C6H10) (6) is obtained.As for 3, only one diene C=C bond is coordinated to nickel(0), but the structure is fluxional with exchange of the coordinated and unbound C=C bonds (NMR at 20 degC).From a solution of 6 in pentane the dinuclear, diastereomeric compounds rac/meso-tBu2PC2H4PtBu2)Ni>2(μ-η2,η2-C6H10) (7a,b) separate in large yellow crystals.In similar reactions the 1,6-heptadiene complexes (tBu2PC2H4PtBu2)Ni(η2-C7H12) (8) and rac/meso-tBu2PC2H4PtBu2)Ni>2(μ-η2,η2-C7H12) (9a,b) are also obtained.In 6, 7a,b, 8, and 9a,b the open-chain diene ligands can easily be displaced, e.g., by ethene to afford 5.Thus, complexes 6, 7a,b, 8, 9a,b are the most reactive.These complexes react readily (the ethene derivative 5 also reacts but very slowly) with butadiene to yield large yellow cubes of (tBu2PC2H4PtBu2)Ni(η2-C4H6) (10), which is also fluxional.The alkene complexes 5, 6, 7a,b, 8, 9a,b, 10 react with ethyne to yield yellow-brownish crystalline (tBu2PC2H4PtBu2)Ni(C2H2) (11).Key Words: Alkenens, Ethyne, Nickel(0), Phosphane, X-Ray
