General description

cis-1,2-Cyclooctanediol is a 1,2-disubstituted acyclic ethylene glycol.[1] It undergoes cyclocondensation with oxalyl chloride in the presence of triethylamine at 0°C to yield cyclic oxalate.[1]

Application

cis-1,2-Cyclooctanediol may be used in the preparation of suberic acid.[2]

The role played by the additives salicylic acid, L-ascorbic acid and oxalic acid in promoting the catalytic activity of [MnIV2(O)3(tmtacn)2](PF6)2 (1(PF6)2, where tmtacn = N,N',N''-trimethyl-1,4,7-triazacyclononane) in the epoxidation and cis-dihydroxylation of alkenes with H2O2 and in suppressing the catalysed decomposition

The relationship between the product patterns and the configurations of 1,2-cycloheptane- and 1,2-cyclooctanediols 9 in the cyclocondensations with oxalyl chloride in the presence of triethylamine at 0 degrees C has been shown analogous to that obtained for 1,2-disubstituted acyclic ethylene
