以VO(Acac)_2为代表的酰(氧)钒配合物催化H_2O_2或ROOH氧化烯烃等有机底物的反应历程涉及双氧物种与V形成的中间物的观点已被普遍接受,因此,如果能利用分子O_2与V形成双氧钒配合物,则有可能利用O_2代替H_2O_2或ROOH作为催化氧化有机底物的原料.1978年,Wilshire和Sawyer报道了用谱学方法发现酰(氧)钒配合物与O_2形成双氧钒配合物,但后来Cooper,Koh和Raymond对该报道产生了怀疑,并对该体系重新进行了研究,结果否定了Sawyer等人的报道.Bosserman和Sawyer也没能重复得到该报道中的合成和
The reaction of an acyl (oxy) vanadium complex such as VO (Acac) 2 catalyzed by an organic substrate such as H 2 O 2 or ROOH to oxidize olefins has been generally accepted as involving intermediates formed between the dioxygen species and V, and therefore, It is possible to use O 2 instead of H 2 O 2 or ROOH as a starting material for the catalytic oxidation of organic substrates by forming a complex of vanadyl with molecules O 2 and V. In 1978 Wilshire and Sawyer reported that spectroscopic methods found that the acyl (oxy) vanadium complex Formed a vanadyl complex with O 2, but later Cooper, Koh, and Raymond cast doubt on the report and re-studied the system, negating the report of Sawyer et al.23 Bosserman and Sawyer also failed to obtain the Reported in the synthesis and
