Methane and derivs

Dichloronitromethane. This article supplements the material in Vol 5, D1213-R under Dichloro-methane and Derivatives. In polarographic analysis it shows a complex curve indicating two 2-electron reductions giving finally NMe and two Cl ions (Ref 1). Its pKa at 25° was found to be 5.99 (Ref 2)... 

Nitrocarbol. Same as Nitromethane. See under Methane and Derivatives in this Vol... 

Polynitrodiphenylmethanes. See Diphenyl-methane and Derivatives in Vol 5, D1464-L to D1466-L. Hexanitrodiphenylmethane had not been synthesized as of 1966. However, since then the work of Shipp and Kaplan (Ref 2) in 1976 allows the following entry to be made ...

Chlorodinitromethane. This article supplements the material in Vol 3, C259-L under Chloro-methane and Derivatives CA Registry No 921rl3-l. Its pKg in w at 20P is 3 53-3.80 (Refs 1 3). The K salt has a mp of 8 with decompii (Ref 2). The Hg salt is prepd from chlorodinitromethane and the Hg s t of fluorodinitromethane. It reacts with aniline to form PhNHC(N02)2Cl. yield 59.1%, mp i25° with decompn (Ref 4)... 

Computational chemists will readily attest that it is nowadays hard to compute metal clusters but trivial to compute ground state closed-shell organic molecules. On the other hand, we have seen that it is equally hard to understand the electronic structures of metals and alkanes. The MOVE formulas for methane and derivatives differ from the Lewis structure ip a fundamental way ...
