1-octene, 1-nonene, cyclohexene and cyclooctene with tris(2,4-pentanedionato)manganese(III) in acetic acid at room temperature give 4-acetyl-3-hydroxy-3-methyl- 1,2-dioxacyclohexanes in 8–92 % yields. The reactions of 1,1-disubstituted ethenes with ethyl 3-oxobutanoate or acetoacetanilide in the presence of manganese(III) acetate also give cording 1,2-dioxacyclohexanes in good to moderate yields.
1,1-二取代的乙烯,苯乙烯,1-辛烯,1-壬烯,环己烯和环辛烯与三(2,4-戊二酮基)锰(III)在乙酸中于室温反应生成4-乙酰基-3-羟基-3-甲基-1,2-二氧杂环己烷的产率为8–92%。在乙酸锰(III)存在下,1,1-二取代的乙烯与3-氧代丁酸乙酯或乙酰乙酰苯胺的反应也以良好至中等的产率得到了1,2-二氧杂环己烷。
