Complex formation of trinitromethane and 1,1-dinitroethane with etheetype solvents

Abstract

1. C-H acids of a number of polynitroalkanes with ether-type solvents form intermolecular hydrogen bonds, forming stable complexes with a 1∶1 composition. 2. The replacement of the methyl group in the α-position of C-H acids by a nitro group increases their proton donor capacity and the energy of the hydrogen bond, 3. The change in the structure of the investigated ethers-hydrogen acceptors — leads to a change in the value of the dissociation constant of the complexes and does not affect the shift of the C-D band and, consequently, the energy of the hydrogen bond.
