- 論文の詳細を見る
The thermal rearrangement of 2,3-bis(alkylimino)oxetane (<B>1</B>) was investigated. At 200°C, 2,3-bis(secondary alkylimino)oxetane was converted into 3-imidazolin-5-one (<B>8</B>). 2,3-Bis(tertiary alkylimino)oxetane was stable at 200°C, but it was rearranged at 300°C to a cyclobutanone derivative (<B>18</B>). A mechanism involving the β-lactam intermediate (<B>12</B>) (<B>17</B>) formed by the Chapman rearrangement of <B>1</B> was proposed.
