Organic superbases are mostly charge-neutral, nitrogen containing species, where nitrogen act as a proton acceptor. These include the phosphazenes, phosphanes , amidines, and guanidines. Other organic compounds that meet the physicochemical or structural definitions of 'superbase' include proton chelators like the aromatic proton sponges and ...
Well known phosphazene bases are BEMP (2-tert-Butylimino-2-diEthylamino-1,3-diMethylperhydro-1,3,2-diazaPhosphorine) with an acetonitrile pK a of the conjugate acid of 27.6 and the phosphorimidic triamide t-Bu-P 4 (pK BH + = 42.7) also known as Schwesinger base. [2]
7-Methyl-1,5,7-triazabicyclo[4.4.0]dec-5-ene (mTBD) is a bicyclic strong guanidine base (pK a = 25.43 in CH 3 CN and pK a = 17.9 in THF). [3] mTBD, like 1,5,7-triazabicyclo[4.4.0]dec-5-ene and other guanidine super bases, can be used as a catalyst in a variety of chemical reactions. [4]
The high reactivity of Schlosser's base is exploited in synthetic organic chemistry for the preparation of organometallic reagents. For example, potassium benzyl can be prepared from toluene using this reagent. Benzene and cis/trans-2-butene are also readily metalated by Schlosser's base. Toluene, benzene, and butenes react only slowly with ...

Natural Balance began in 1989 when Van Patten was a guest on John Davidson's show. Van Patten had lunch with the show's band drummer, Joey Herrick, [2] who rescued dogs and cats. Van Patten told him when he was a kid he had snakes, alligators, and other animals. The drummer and Van Patten had an idea of making a health food for dogs.
