Specific deuterated reference compounds were prepared to probe the stereoselectivity of the reductive ring opening of carbohydrate-based benzylidene-type acetals. AlD(3) revealed a retentive stereoselectivity probably through the rare S(N)i (internal nucleophilic substitution) mechanism. An S(N)1-like mechanism occurs in the acid-promoted

Nanoarchitecture of Protective Coatings for Air Sensitive Metal Hydrides

Our research impacts on the hydrogen energy economy through the development of “smart” nanofilms for the protection of metal hydrides against air and moisture, while permitting release of hydrogen gas through these semi permeable nanofilms.
