Naphthalene-1,5-diylbis(diphenylphosphine oxide), also known as NDI-BP, is a chemical compound with the molecular formula C34H26OP2. It is a white crystalline solid that is widely used as a ligand in the synthesis of transition metal complexes, particularly in the field of homogeneous catalysis. The compound features a naphthalene core with two diphenylphosphine oxide groups attached at the 1 and 5 positions, providing a rigid and planar structure that can effectively stabilize metal centers. NDI-BP is known for its strong electron-donating properties and its ability to form stable complexes with various metals, making it a valuable tool in the development of new catalysts and materials for applications such as olefin polymerization, hydrogenation, and cross-coupling reactions.

3095-34-9 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 3095-34-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,0,9 and 5 respectively; the second part has 2 digits, 3 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 3095-34:
(6*3)+(5*0)+(4*9)+(3*5)+(2*3)+(1*4)=79
79 % 10 = 9
So 3095-34-9 is a valid CAS Registry Number.

C-P bond-forming reactions via C-O/P-h cross-coupling catalyzed by nickel

Yang, Jia,Chen, Tieqiao,Han, Li-Biao

, p. 1782 - 1785 (2015)

The first Ni-catalyzed C-O/P-H cross-coupling producing organophosphorus compounds is disclosed. This method features wide generality in regard to both C-O and P-H compounds: for C-O compounds, the readily available alcohol derivatives of aryl, alkenyl, benzyl, and allyl are applicable, and for P-H compounds, both >PV(O)H compounds (secondary phosphine oxide, H-phosphinate, and H-phosphonate) and hydrogen phosphines (>PIIIH) can be used as the substrates. Thus, a variety of valuable C(sp2)-P and C(sp3)-P compounds can be readily obtained in good to excellent yields by this new strategy.
