The London and North Eastern Railway Class P1 Mineral 2-8-2 Mikado was a class of two steam locomotives designed by Nigel Gresley. They were two of the most powerful freight locomotives ever designed for a British railway. It was initially intended they be a more powerful 2-10-0 version of the earlier Class O2 2-8-0s.

1,3-Bis(diphenylphosphino)propane (dppp) is an organophosphorus compound with the formula Ph 2 P(CH 2) 3 PPh 2. The compound is a white solid that is soluble in organic solvents. It is slightly air-sensitive, degrading in air to the phosphine oxide. It is classified as a diphosphine ligand in coordination chemistry and homogeneous catalysis.

It is often used with triphenylphosphine in the Mitsunobu reaction, [2] wherein it serves as a hydride acceptor. It has also been used to generate aza- Baylis-Hillman adducts with acrylates. [ 3 ] It can also serve as a selective deprotectant of N- benzyl groups in the presence of other protecting groups.
1,2-Bis(diisopropylphosphino)ethane (dippe) is a commonly used bidentate ligand in coordination chemistry. This compound is similar to the ligand 1,2-bis(diphenylphosphino)ethane (dppe), with the substitution of isopropyl groups for phenyl groups.
