Tri-nitro Tri-phenyl Methane.—When tri-phenyl methane is nitrated a tri-nitro tri-phenyl methane is obtained in which one nitro group enters each benzene ring. 

Commercial ISEs are made with liquid membranes involving both ion-exchanging systems and ionophores (see table 9.7). The solvent used is a hydrophobic liquid with a low relative permittivity. Examples include decane-l-ol, 5-phenyl pen tan-2-01, octyl phtalate, tri-n-phenyl phosphate, and 2-nitro-/ -cymene. Another important property of the solvent is that it have a low vapor pressure so that it is not...

Zm complex (45) provided a model for the Zm -activated serine of AP (see Scheme 10). An alkoxide group in (45b) attacked BNPP to give a phosphorylserine intermediate (46), which was susceptible to further hydrolysis by the intramolecular Zn -bound hydroxide in (46b) to give (47) (Scheme 33). For the first step, the alcohol group is deprotonated by the proximate Zn (p7 a = 7.5) to an alkoxide complex (45b), which was 125 times more effective as nucleophile to the phosphate substrate than was the Zn -activated water of the reference compound (34). For the subsequent step, the nucleophilic Zn species (46c) was generated with a pXa value of 9. This intramolecular hydrolysis is 45,000 times faster than the intermolecular hydrolysis of ethyl 4-nitro-phenyl phosphate (ENP) with (34b). These results imply an advantage of the intramolecular arrangement of two Zn ions in AP (as shown in Scheme 10) over mononuclear Zn hydrolases. Toward any mononuclear Zn phosphatase model, phosphomonoesters were not substrates, but instead were inhibitors, as shown by isolation of the stable complexes (43), (44), and (47). The tris(pyrazolyl)-hydroborate complexes such as (35) and (38) hydrolyze phosphodiesters to phosphomonoesters, which similarly bind to Zn to become inert to further hydrolysis. ...
