Application of bis(diphenylphosphino)ethane (DPPE) in Staudinger-type N-glycopyranosyl amide synthesis.

David P Temelkoff et al.

Carbohydrate research, 341(10), 1645-1656 (2006-02-28)

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

The reaction of [Fe2(CO)6(mu-SCH2)2NCH2CH2N(mu-SCH2)2Fe2(CO)6] (1) with 1,2-bis(diphenylphosphino)ethane in the presence of Me3NO.2H2O affords two structurally different metallomacromolecules: a dimer of the type [{Fe2(CO)5(mu-SCH2)2NCH2CH2N(mu-SCH2)2Fe2(CO)5}(Ph2PCH2)2] (2) and a tetramer species containing eight iron centers with an overall formula of [{Fe2(CO)6(mu-SCH2)2NCH2CH2N(mu-SCH2)2Fe2(CO)5}2(Ph2PCH2)2] (3).
