DOCUMENT TYPE: Journal CA Section: 28 (Heterocyclic Compounds (More Than One Hetero Atom)) Reaction of 9,10-phenanthrenequinone (I) with PhCH2NH2 gave the phenanthrimidazole or -oxazole II (R = Ph, X = NCH2Ph, O, resp.), whereas in the presence of p-R1C6H4CHO (R1 = MeO, O2N), II (R = C6H4R1-p, X = NC6H4R1-p, O) were obtained.In this experiment, several chemicals are used like 555-16-8 and 14132-51-5 With BuNH2, I gave II (R = Pr, X = O). .

The triplet state decay (T1(np*) ? S0) of benzaldehydes in the dilute gas phase

The triplet state decay (T1(np*) ? S0) of benzaldehydes in the dilute gas phase. Bruehlmann, U.; Nonella, M.; Russegger, P.; Huber, J. Robert (Phys. Chem. Inst., Univ.

DOCUMENT TYPE: Journal CA Section: 22 (Physical Organic Chemistry) The triplet T1 (np*) decay of benzaldehyde (B) and its isotopomers B-d1, B-d5, and B-d6 were investigated in the dil. vapor phase (￡0.5 Torr) at room temp. Following S1(np*)?S0 excitation the quantum yields of the phosphorescence and photodecompn., and the rate consts. of the phosphorescence and the radiationless T1 ?S0 process were detd. Based on these results and in conjunction with theor. calcns. of T1 ?S0 rates and previous data obtained on propynal, the decay mechanism of benzaldehyde was analyzed. The important accepting modes of the non-radiative T1 ?S0 decay are the C-Hald wagging and the C:O stretching modes. In spite of the close vicinity of the T2(pp*) and the T1(np*) states, the non-adiabatic coupling (communication between ring and carbonly vibrations) is not sufficient to influence the relaxed T1(np*) decay significantly. .
