The C-C bond cleavage of terminal and internal diynes takes place readily in the presence of catalytic amounts of Ru3(CO)12 or Pd(NO3)2 and of 2-aminophenol, giving the corresponding benzoxazoles and ketones in good to high yields. There are two different modes of the bond cleavage: (a) an alkyne C-C triple bond is cleaved, and (b) the C-C single bond between the two alkyne groups is cleaved.
在催化量的 Ru3(CO)12 或 Pd(NO3)2 和 2-氨基苯酚存在下,末端和内部二炔的 CC 键断裂很容易发生,从而以良好或高产率得到相应的苯并恶唑和酮。有两种不同的键断裂模式:(a) 炔烃 CC 三键断裂,和 (b) 两个炔基之间的 CC 单键断裂。
