4-dihydropyridine reacts with ketones and aldehydes to give products of N–Si addition across the C═O bond. Hydrosilylation of pyridine in acetone results quantitatively in the addition product PhMe2SiO–CMe2–NC5H6, which decomposes in hexane to give the parent dihydropyridine HNC5H6. The phenanthroline complex [Cp(phen)Ru(NCCH3)2]+ (10) catalyzesregioselective 1,4-reduction of phenanthroline by a 3–4-fold excess

Not only surprisingly facile, a hydrosilylation of pyridines under the catalysis of [Cp(iPr3P)Ru(NCCH3)2]+ has the advantages that it is 1,4‐regioselective and reversible. The products can be transformed in a variety of ways (see scheme). The related complex [CpRu(NCCH3)3]+ catalyzes the two‐hydrogen‐atom reduction of phenanthroline by HSiMe2Ph/water.
The present disclosure discloses a deuterated organic compound and a formulation and an organic electronic device containing the same, wherein the deuterated organic compound has the following structural formula:
wherein Ar is an aromatic or heteroaromatic structural unit, D is an electron donor group, A is an electron acceptor group, n and m are an integer between 1 and 6; and wherein for the organic compound, (S1−T1)≤0.25 eV, and at least one H atom of the organic compound is substituted by deuterium.
