Copper-catalysed rearrangement of 4-substituted-2,3-1H-benzoxazine-1-thiones
, 2000 4-Substituted-2,3-1H-benzoxazine-1-thiones were prepared by the treatment of the corresponding benzoxazine-1-ones with P2S5. The thermal rearrangement of 4-substituted-2,3-1H-benzoxazine-1-thiones, catalysed by metallic copper, yielded 4-substituted-2,3 ...

Chiral Bidentate (Phosphinophenyl)benzoxazine Ligands in Asymmetric Catalysis
, 2001 The new chiral bidentate (phosphinoaryl)benzoxazine ligands 2 were applied in asymmetric catalysis. Rhodium and copper complexes catalyzed the hydrosilylation of acetophenone and [4+2] cycloadditions with moderate enantioselectivity.

Synthesis and characterization of chalcone-containing benzoxazine
, 2018 本論文使用含有chalcone結構之雙酚單體，成功製備出雙官能的氧代氮代苯并環己烷(Benzoxazine)單體(2)。將合成之 Benzoxazine 單體以紫外光照射，探討其雙鍵因受光激發進行[2+2]環加成(cycloaddition)反應及其結構變化。 此外，為了瞭解光交聯機制對於整體熱性質與機械性質的影響，將照光後的Benzoxazine 單體(2)進行加熱固化，使雙鍵進行環加成反應後，再升溫固化使得Benzoxazine開環，進而得到交聯之網狀結構，因此在材料測試方面，由於其交聯密度的提升 ...
