The reaction yields were quite low due to the instability of the methylacetal protecting group towards borane
reagent and the problems with handling volatile intermediate compounds.
melts at 104#161#C, whereas ethane (H3CCH3), which has an analogous structure but features no dihydrogen bonding, melts at -181#161#C.
Now the team has developed a catalyst system that releases enough hydrogen from its storage in ammonia borane
to make it usable as a fuel source.
has a large fraction of hydrogen that can be released as a gas, the laboratory said.
Axonal polyneuropathy after acute dimethylamine borane
Many other nucleic acid labels have been proposed recently, including borane
hydride compounds, which are detected via reduction of a metal ion (e.
Oxiranes, acetals, esters, nitriles, amines, amides, nitro, ketone, carbamate, ether, isocyanate, phosphate, phosphonic dichloride, dialkoxy borane
, sulfide, sulfone, or carborane groups can be present without reacting (2).
Hypercoordinate Carbocations and Their Borane
(CAS 74-94-2) Market Research Report 2009
The technique uses the Lewis acid tris(pentafluorophenyl) borane
and the Lewis base tetramethylpiperidine that have been modified to be too large to get close enough to form an adduct (Lewis bases, which carry a lone pair of electrons, can bond with Lewis acids to form molecules called adducts).
