The 1,5-cyclooctadiene - palladium chloride complex and carbon monoxide react in ethanol to form ethyl 4-cyclooctenecarboxylate. The carbonylation of 1,5-cyclooctadiene catalyzed by palladium chloride has given ethyl 4-cyclooctenecarboxylate and cyclooctanedicarboxylate. It has been found that the monoester can be obtained selectively under certain conditions; the further carbonylation of the monoester
1,5-环辛二烯-氯化钯络合物和一氧化碳在乙醇中反应生成4-环辛烯羧酸乙酯。氯化钯催化 1,5- 环辛二烯的羰基化反应得到 4- 环辛烯羧酸乙酯和环辛二羧酸乙酯。已经发现在一定条件下可以选择性地获得单酯;单酯的进一步羰基化得到二酯。在相同的反应条件下,1,3-环辛二烯以低产率得到2-环辛烯羧酸乙酯。已经发现金属钯是真正的催化剂,并且已经发现氯化氢的存在对于催化是必不可少的。还发现1,5-环辛二烯-氯化钯络合物可由1,5-环辛二烯形成,通过在氮气下的高压釜中加热金属钯和氯化氢。1,5-环辛二烯的催化羰基化似乎是通过形成1,5-环辛二烯-pa...
