The combination of variable temperature (190-297 K) IR and NMR spectroscopy studies with quantum-chemical calculations at the DFT/B3PW91 and AIM level had the aim to determine the mechanism of proton transfer to CpRuH(dppe) (1, dppe = Ph(2)P(CH(2))(2)PPh(2)) and the structures

The molybdenum(V) complex [Mo(O)Cl(3)dppe] [dppe = 1,2-bis(diphenylphosphino)ethane] is considered as a model system for a combined study of the electronic structure using UV/vis absorption and magnetic circular dichroism (MCD) spectroscopy. In order to determine the signs and MCD C-term intensities

Bis(diphenylphosphine)ethane (DPPE) and its gold coordination complexes have demonstrated antitumor activity in transplantable tumor models. This report describes the development of a P388 cell line (P388/DPPEc) that is resistant to DPPE and its analogues and the in vitro characterization of

The cytotoxic properties of arylphosphines are regulated by metals. We have synthesized a series of copper(I) complexes of 1,2-bis(diphenylphosphino)ethane (DPPE) and tested their in vitro cytotoxicity in a human lung carcinoma cell line H460. One of the complexes [Cu(2)(DPPE)(3)(CH(3)CN)(2)](ClO(4))(2) (C1)

Bis(diphenylphosphino)ethane (DPPE) reacts with pyranosyl azides derived from D-glucose and D-glucuronic acid in the presence of acid chlorides to yield the corresponding glycosyl amides. Reaction rates are comparable to those with triphenylphosphine, however, the byproduct phosphine oxide is easily removed
