Organosubstitutierte 1,6-Dioxa-2-sila-5-bora-3-cycloalkene - Herstellung und Charakterisierung

Organosubstituted 1,6-Dioxa-2-sila-5-bora-3-cycloalkenes - Preparation and Characterisation The cis alkenes ROSi(CH3)2C(R)=C(C2H5)B(C2H5)OR (R=CH3: 11; C2H5: 12; C6H5: 13) are prepared from CH3NSi(CH3)2C(R)=C(C2H5)BC2H5 A; R=C(CH3)=CH2: B> with the monohydroxy compounds ROH (R= CH3, C2H5, C6H5).A or B react with aliphatic dihydroxy compounds HO-R'-OH to give 8-,9-, and 10-membered ring compounds OSi(CH3)2C(R)=C(C2H5)OR'.A is initially cleaved at the SiN bond with formation of 14.Compound 15a crystallises as the 16-membered (15a)2 (X-ray structure analysis).The aromatic dihydroxy compounds catechol (7), resorcinol (8), 2,3-dihydroxynaphthalene (9), 1,8-dihydroxynaphthalene (10) react with A to form 21 to 24, but mainly by protolytic BCvinyl fission to give the 2,5-dihydro-1,2,3-dioxaboroles (e.g. 7f1, 9f1, 10f1) and the acyclic boron-free compounds 7f3, 9f3, 10f3 or the dyotropic rearranged isomers 7f3', 9f3', 10f3'.The MS and NMR (1H, 11B, 13C, 29Si) data of the new compounds are discussed.

Process for the separation and purification of oligo and polyhydroxy compounds and borate esters thereof

A process for the separation and/or purification of oligo- and polyhydroxy compounds by introducing and subsequently eliminating protective groups, wherein oligo- and polyhydroxy compounds are reacted with bis(ethyl-pivaloyloxy)-diboroxane or ethylboroxine, optionally in inert solvents, the resulting O-ethylboranodiyl derivatives of the hydroxy compounds are separated off and the O-ethylboranodiyl protective groups are eliminated by alcoholic compounds, for example methanol or glycol.
