ABSTRACT
The article focuses on the semi-metal hydride generation mechanism that invoke the formation of nascent hydrogen. According to nascent hydrogen theory, nascent hydrogen is formed during acid decomposition of borohydride, and it is responsible for the derivation of the element to the hydride, which can be validated by the use of deuterium-labeled reagents. A brief history of arsenic used as poison and its discovery through tests are provided.

    The abstraction of chemisorbed deuterium (D) on Si(100) by atomic hydrogen (Hat) is studied in real time. The surface H and D coverages are measured by mass analyzing the recoiled H+ and D+ ion signals during the abstraction reaction. We find that Hat efficiently removes adsorbed D on Si(100)...

    2-(1-Hydroxybenzyl)-N1′-methylthiamin (1b) is a model for the addition intermediate in the thiamin catalyzed benzoin condensation. However, N-alkylation alters the reactivity of the compound: instead of undergoing base-catalyzed formation of benzaldehyde and N1′-methylthiamin, it...
