Sodium hydride is the chemical compound with the empirical formula Na H.This alkali metal hydride is primarily used as a strong yet combustible base in organic synthesis.NaH is a saline (salt-like) hydride, composed of Na + and H − ions, in contrast to molecular hydrides such as borane, silane, germane, ammonia, and methane.
n.o.s. = not otherwise specified meaning a collective entry to which substances, mixtures, solutions or articles may be assigned if a) they are not mentioned by name in 3.2 Dangerous Goods List AND b) they exhibit chemical, physical and/or dangerous properties corresponding to the Class, classification code, packing group and the name and description of the n.o.s. entry [2]
Since many substrates are not stable to sodium hydride, several procedures have been developed using milder bases. Masamune and Roush have developed mild conditions using lithium chloride and DBU. [18] Rathke extended this to lithium or magnesium halides with triethylamine. [19]
Sodium bis(2-methoxyethoxy)aluminium hydride (SMEAH; [1] trade names Red-Al, Synhydrid, Vitride) is a hydride reductant with the formula NaAlH 2 (OCH 2 CH 2 OCH 3) 2. The trade name Red-Al refers to its being a reducing aluminium compound. It is used predominantly as a reducing agent in organic synthesis.
A sample of sodium hydride. Hydrogen compounds are often called hydrides, a term that is used fairly loosely. The term "hydride" suggests that the H atom has acquired a negative or anionic character, denoted H −; and is used when hydrogen forms a compound with a more electropositive element.
