The Study Of Interaction Between A Protonic Hyfrogen And A Hydridic Hydrogen

With the improvement of the scientific and technology, development of economic and promotion ofhuman living standards, fossil fuel energy consums excessively, human beings are facing increasinglyserious energy crisis and environmental problems all over the world, therefore, it’s urgent to explore somesuitable new energy sources which are non-polluting and energy-efficient that can alternative to fossil fuelenergy. Hydrogen has attracted considerable attention because of its abundant raserves, combustionproducts are clean, high energy density and can provide highly efficient and stable power source. How tostore hydrogen safely and efficiently and achieve completely control is the barrier for its practicalapplication. People are exploring hydrogen storage materials with high volume, high quality hydrogenstorage density actively. B-N-H compounds with high hydrogen content, appropriate stability, idealhydrogen release temperature, certain reversible regeneration function, become a great potential chemicalhydrogen storage material.Since Alfred Stock who is known as the father of boron chemistry has made pioneering work in boronchemistry, the borane complex have played an important role in chemistry. Borane is an excellent reducingagent, their most widely applications is on drugs synthesis which has important practical value, they arealso widely used in reducing the unsaturation bonds in organic reactions, such as the double bond betweenthe carbon and nitrogen, carbon and carbon, carbon and oxygen. Some borane have received more andmore attention as a high hydrogen content itself, or realease a considerable volume of hydrogen by reactionwith other compound.The dissertation reviewes the research progress and development of the hydrogen storage material,Lewis acid-base theory, application of the reactions of the acid-base, summarizes the practical significanceof the neutralization reaction. The combination reaction between a protonic hydrogen and a hydridichydrogen is a special neutralization reaction. Dihydrogen bond is an electrostatic interaction between aprotonic hydrogen of a hydrogen bond donor HX (X=F, O, N) and a hydridic hydrogen from a hydrogenbond acceptor which has an important influence in the amine borane chemistry. Dihydrogen bond has agreat influence on the structure, mechanism of the amine borane chemistry. The influence fator on strength of dihydrogen bond and application on the molecule’s structure and chemical reactivity are not been paidenough attention, especially the applications in synthetic chemistry. We give an review on the structure,chemical reaction, applications of ammonia borane, and brief introduction on chemical reactions andconcrete application in medicine of other lewis base boranes, such as dimethylaniline borane,dimethylsulfide borane, tetrahydrofuran borane.Based on the research of boron chemistry, hydrogen storage materials and dihydrogen bond which isthe electrostatic interaction between a protonic hydrogen of a hydrogen bond donor and a hydridichydrogen from a hydrogen bond acceptor, we selected nearly40kinds of lewis acid which can provideprotonic hydrogen(such as alcohols, phenols, sugars, etc) react with some Lewis acid-base adducts whichcan provide hydridic hydrogen (ammonia borane, N,N-dimethylaniline borane, dimethylsulfide borane,borane tetrahydrofuran). By observing experiments phenomenon, we analyzed the influence of temperatureand solvent on the reaction rule, we preliminarily explores the strength of lewis base and lewis acid’seffection on dihydrogen bond and conditions that lead to hydrogen generation. The rule of interactionbetween a protonic hydrogen and a hydridic hydrogen has been preliminary studied. Experimental resultsshow that weakest lewis base, ammonia borane can hardly react with weak proton donor compound, butslowly with active hydrogen proton donor compound. Other borane can react with weak proton donorcompound varying degrees. When the electrostatic between protonic hydrogen and hydridic hydrogen isstrong enough, they can combine to hydrogen gas. With borane`s alkalinity increase, the reaction is morethorough, indicate the hydridic hydrogen that connect with boron is more stable, the borane’s reactivity ismore weak. In addition, we explored the synthesis a new kind of borane, borane-phenylenediamine, and aboron-contained polymer compound was discovered.
