Hindered rotation in amidines

Journal of Molecular Structure, 1990
Abstract The 15N chemical shifts and frequencies of νCN bond from Raman spectra of N1N1-dimethyl-N2-substituted amidines were related to the rotational barriers around CN1 bond obtained from 13C NMR.

The Nonenzymatic Decomposition of Guanidines and Amidines

Journal of the American Chemical Society, 2013
To establish the rates and mechanisms of decomposition of guanidine and amidine derivatives in aqueous solution and the rate enhancements produced by the corresponding enzymes, we examined their rates of reaction at elevated temperatures and used the Arrhenius equation to extrapolate the results to room temperature.

Synthesis and characterisation of sterically bulky lithium amidinate and bis-amidinate complexes

Journal of Organometallic Chemistry, 2006
Abstract The synthesis and characterisation of the amidines, (tript)C(NR)(NHR), R = Pr i or cyclohexyl (Cy), tript = triptycenyl, and lithium amidinate complexes, [Li(THF) 2 {(tript)C(NR) 2 }] bearing the bulky triptycenyl substituent on the amidine or amidinate backbone carbon is described.

Advances in the Chemistry of Amidines

Russian Chemical Reviews, 1983
The review surveys data published during the period 1971–1981 on the synthesis and physicochemical and chemical properties of various types of amidine systems. Particular attention has been devoted to the use of amidines in the synthesis of heterocycles. The bibliography includes 259 references.

The Anesthetic Activity of Some Amidines*

Journal of the American Pharmaceutical Association (Scientific ed.), 1954
The anesthetic activity of some esters of p carboxybenzamidine and N-alkyl p-carboxy-benzamidine have been reported. Mention is also made of their bactericidal and antispasmodic activities.
