Diketones are regioselectively prepared from alkynyl ketones under mild conditions by palladium catalysis; 5-heptyn-2-one and 2-(2-nonynyl)cyclohexanone give 1,4-dikektones whereas 2-(2-heptynyl)cyclopentanone and 5,6-didehydroprostaglandin E2 methyl ester afford 1,5-diketones.
在温和条件下,通过钯催化,从炔基酮区域选择性地制备二酮。5-庚炔-2-酮和2-(2-壬炔基)环己酮生成1,4-二酮,而2-(2-庚炔基)环戊酮和5,6-二氢氢化前列腺素E 2甲酯生成1,5-二酮。
