The current climate crisis has reignited the interest for MP, which is even used for human consumption (e.g. Quorn™, Marlow Foods, UK), suggesting the emergence of a paradigm shift that could enable the generation of more sustainable food-protein products. This approach could result in ...
Intermediate 382 ideally positions the hydrogen of the isoborneol for an 1,7-hydride shift in analogy to an intramolecular MVP-reduction to produce 383. The authors comment that with aromatic substituents at position R1 and R2 desulfurization with Raney-Ni to 384 occurred without racemization of ...
The 3-methylcyclopentene and 3-methylcyclohexene monomers polymerize (at least partly) by 1,3-addition following a 3,2-hydride shift. The 3-methylcyclohexene polymers are also partly crystalline and have birefringence melting points between 200 and 250掳C. Little ring-opening polymerization of the...
Reaction of pentacarbonylrhenium hydride with hexafluorobuta-1,3-diene gives a crystalline 1 : 1 adduct CHF2·CF2·CF:CF·Re(CO)5(Ia) corresponding to a 1,4-addition followed by a 1,3-fluorine shift. Pentacarbonylmanganese hydride reacts... BW Tattershall,AJ Rest,M Green,... - 《Journ...
Domino reactions initiated by intramolecular hydride transfers from tri(di)arylmethane fragments to ketenimine and carbodiimide functions. The ability of triarylmethane and diarylmethane fragments to behave as hydride donors participating in thermal [1,5]-H shift/6蟺-ERC tandem processes invol... Mat...
Ketal 42 was transformed into norbornenone 45 in three steps (at 58.7% yield over three steps): diisobutylaluminum hydride-based reduction of the ester of 42 to the corresponding 1° alcohol of 43, and subsequent deprotection of the ketal to form 44, and silyl protection of the 1° alcohol...
The formation of hydride from hydrogen molecule is associated with the concept “molecular hydrogen-originated protonic acid” [3]. Binomial distribution of D atoms in methylcyclopentane results from repeating the forward and backward reaction of the H- (or D-) transfer step to form methyl...
