Simple unprecedented conversion of phosphine oxides and sulfides to phosphine boranes using sodium borohydride.
A variety of phosphine oxides and sulfides can be efficiently converted directly to the corresponding phosphine boranes using oxalyl chloride followed by sodium borohydride. Optically active P-stereogenic phosphine oxides can be converted stereospecifically to phosphine boranes with inversion of configuration by treatment with Meerwein's salt followed by sodium borohydride.
متن کاملAmine-boranes bearing borane-incompatible functionalities: application to selective amine protection and surface functionalization.
The first general open-flask synthesis of amine-boranes with inexpensive and readily available reagents, such as sodium borohydride, sodium bicarbonate, water, and the desired amines is described. Even amines bearing borane-reactive functionalities, such as alkene, alkyne, hydroxyl, thiol, ester, amide, nitrile, and nitro are well tolerated. Some of these novel amine-boranes represent stable mo...
متن کاملAmine-boranes: green hypergolic fuels with consistently low ignition delays.
Complexation of amines with borane converts them to hypergols or decreases their ignition delays (IDs) multifold (with white fuming nitric acid as the oxidant). With consistently low IDs, amine-boranes represent a class of compounds that can be promising alternatives to toxic hydrazine and its derivatives as propellants. A structure-hypergolicity relationship study reveals the necessary feature...
متن کاملIron Catalyzed Dehydrocoupling of Amine‐ and Phosphine‐Boranes
Catalytic dehydrocoupling methodologies, whereby dihydrogen is released from a substrate (or intermolecularly from two substrates) is a mild and efficient method to construct main group element-main group element bonds, the products of which can be used in advanced materials, and also for the development of hydrogen storage materials. With growing interest in the potential of compounds such as ...
متن کاملDehydrogenation of amine-boranes with a frustrated Lewis pair.
Bulky tertiary phosphine/borane Lewis pairs P(t)Bu(3)/B(C(6)F(5))(3) react with amine-boranes to afford dehydrocoupling products and phosphonium borohydride salts.
