Very Strong Organosuperbases Formed by Combining Imidazole and Guanidine Bases: Synthesis, Structure, and Basicity

Original language description

New structural motives for organosuperbases, that are easy to prepare and highly basic are urgently required in many areas of chemistry. The synthesis of N,N'-bis(imidazolyl) guanidine bases (BIG bases) is reported. Their pK(alpha) values are determinedas 26.1-29.3 in THF. They are thus probably the strongest known phosphorous-free organic bases both in solution and in the gas phase. Calculations help to determine the structural and electronic factors giving rise to the high basicity.
