X-ray crystal structures of 2,4-dimethyl-4,4a-dihydro-1H-(1,3,5)-triazino(1,2-a)quinoline-1,3,6(2H,5H)-trione and its dehydrogenated derivative. Bond length and EI mass fragmentation.

- 論文の詳細を見る
The crystal structures of the cyclic adduct <B>1</B> of 4-quinolinone with methyl isocyanate and its dehydrogenated derivative <B>2</B> have been determined by X-ray crystal structure analysis. Both crystal structure data of the C–N bond lengths in the triazinedione-ring skeleton suggest which bonds are broken in the initial EI mass fragmentation followed by the subsequent loss of a neutral MeNCO moiety.
