The reaction mechanism of the Sharpless dihydroxylation begins with the formation of the osmium tetroxide – ligand complex (2). A [3+2]-cycloaddition with the alkene (3) gives the cyclic intermediate 4. [9] [10] Basic hydrolysis liberates the diol (5) and the reduced osmate (6).
It can be prepared by base-catalyzed isomerization of 2,3-dimethyl-1-butene. [2] Another route involves direct dimerization of propylene. [3] It can also be produced by photolysis of tetramethylcyclobutane-1,3-dione. [4]
The diallylacetal 3,9-divinyl-2,4,8,10-tetraoxaspiro[5.5]undecane, DVTOSU, is the starting compound for the ketene diacetal 3,9-diethylidene-2,4,8,10-tetraoxaspiro[5.5]undecane, DETOSU, which is formed by shifting the double bonds from the allyl to the vinyl position. [7] DETOSU-Bildungsreaktion

2-Methyl-2,4-pentanediol (MPD) is an organic compound with the formula (CH 3) 2 C(OH)CH 2 CH(OH)CH 3. This colourless liquid is a chiral diol. It is produced industrially from diacetone alcohol by hydrogenation. [4] Total European and USA production was 15000 tonnes in 2000. [5] 2-Methyl-2,4-pentanediol exists as two enantiomers, (4R)-(−) and ...
2,2,4,4-Tetramethyl-1,3-cyclobutanediol (CBDO) is an aliphatic diol. This diol is produced as a mixture of cis - and trans - isomers , depending on the relative stereochemistry of the hydroxyl groups.
The reaction conducted in two steps beginning with the conversion of DMT to the diester dimethyl 1,4-cyclohexanedicarboxylate (DMCD): C 6 H 4 (CO 2 CH 3) 2 + 3 H 2 → C 6 H 10 (CO 2 CH 3) 2. In the second step DMCD is further hydrogenated to CHDM: C 6 H 10 (CO 2 CH 3) 2 + 4 H 2 → C 6 H 10 (CH 2 OH) 2 + 2 CH 3 OH. A copper chromite catalyst ...
