Metal-Ammonia Reduction and Reductive Alkylation of Coal Tar Hydrocarbons and the exp 13 C NMR Characterization and Conformational Analysis of the Reduced Products. Progress Report, December 18, 1978-December 31, 1981

摘要

Progress has been good and has led to a much better understanding of alkali metal reduction processes. Major areas are as follows: (1) Reaction Conditions and Structural Types. Information about the nature of the anionic intermediates (radical anions, monoanions, dianions) has led to an improved method for selecting reaction conditions. (2) Reductive Alkylations. This Sternberg alkylation type process has been investigated with naphthalene and anthracene. (3) Conformational Analysis. Molecular mechanics calculations have been carried out for the reduced hydrocarbons and have produced unexpected results. (4) Protonation Sites in Dianions. Recent results challenge the concept of charge density for predicting protonation sites in dianions. (ERA citation 06:031560)
