On the Reaction of Indole with Sodium Borohydride in Triflueoacetatic Acid

Fast carbon dioxide recycling by reaction with γ-Mg(BH4)2

“…The reaction products can be easily recovered by simple dissolution of the material in water. 25 Fast kinetics of reaction were observed, unexpected on the basis of previous results reported for metal hydrides and ascribable to the large surface area of this material. This clearly indicates that this new class of porous metal hydrides are promising materials for CO 2 recycling.…”

“…Methane and ethylene formation for reaction of CO 2 with alanates has been already reported: 16,17 nevertheless, this reaction has to be carried out at temperature higher than 120°C in order to observe sufficiently fast kinetics. 17 CO 2 reduction by BH 3 NH 3 , LiBH 4 and NaBH 4 was studied previously both theoretically 18 and experimentally, [19][20][21][22][23][24][25][26][27] as a method to enhance the thermolytic dehydrogenation of borohydrate compounds 19,20,27 or as a cheap method to obtain boron-doped carbons 21,22 or graphene oxide. 23 It was also reported that sodium and lithium borohydrides react with CO 2 to give valuable chemical products as formic acid, 26 acyloxyborohydrides 25 and formatomethoxyborate or triformatoborohydride, depending on reaction conditions (temperature and solvents).…”

“…24 The separation of the products from the reagents is possible by simply dissolving the material in a suitable solvent (e.g. water, 25 although this procedure can be safely adopted only after an high degree of CO 2 conversion has been reached to avoid explosions due to the high exothermicity of unreacted borohydrides reaction with water). Nevertheless, the very low reaction rates at RT (1/90 molar ratio of reacted CO 2 /BH 4 after 120 h), 24 make unpractical its industrial application.…”

Sodium borohydride for the near-future energy: a ''rough diamond'' for Turkey

“…110 It can be oxidized and the first study about the direct oxidation of the borohydride anion dates back to the 1950s:…”

Synthesis and reactions of 1-hydroxy-9,9a-dihydro-1H-imidazo[1,2-a]indol-2-(3H)-ones

“…It can be assumed that in the first step of this reductive ring opening, acetic acid promotes cleavage of the annelated lactam moiety leading to the formation of the corresponding 1-[2-(hydroxyamino)-2-oxoethyl]-3H-indolium acetate. Subsequently, in situ generated acetoxyborohydride 36,37 smoothly reduces the iminium group to afford indoline 12. (Figure 6a, b).…”
