2-[2-(dimethylamino)pyrimidin-4-yl]pyridine} is highly reactive in catalyzing the reductive amination of aromaticaldehydes through in situ generated imines with 2-propanol as the hydrogen source following a transfer-hydrogenation mechanism. This transformation does not require any activating additives and is applicable to a broad variety of aldehydes.

extremely strong quadruple NH···N AAAA-DDDD hydrogen-bond array [5·4] (K(a) = 1.5 × 10(6) M(-1) in CH3CN; K(a) > 3 × 10(12) M(-1) in CH2Cl2) features four short linear hydrogen bonds. Changing the two benzimidazole groups of the DDDD unit to triazole groups replaces two of the NH···N hydrogen bonds with CH···N interactions (complex [5·6]), but only reduces the association constant in CH3CN by 2 orders of
