Definitions

  • Z 2 has one of the meanings of Z 1 or is a sirrgle bond .
  • X 1 is O or S
  • X 2 is O, S, SO or SO 2
  • a 1 and A 2 in each case independently of one another are a 1,4-pheny lene group which is unsubstituted or mono- or polysubstituted by halogen atoms and/or CH 3 groups and/or CN groups, it also being possible for one or more CH groups to be replaced by N atoms, a 1,4- cyclohexylene group, it also being possible for one or two non-adjacent CH 2 groups to be replaced by -O- and/or -S-, a piperidine1,4-diyl group, a 1,4-bicyclo[2.2.2]octylene group or a single bond, p i s 0 o r 1 and the symbols R 1 in each case independently of one another are alkyl with 1 to 20 C
  • Vicinai cis-dioles of the formula I can be prepared f.e. by protecting two vicinal cis-OH-groups of the myo-inositol as a cyclic ketal, f.e. a cyclohexylidene ketal, followed by derivating the free OH-grups by one or more of the above mentioned methods and cleaving the ketal.
  • ethylenically unsaturated compounds can also be polymerized by means of metal complexes.
  • metal complexes which are suitable for this are those of aluminium or titanium (Ziegler-Natta catalysts).
  • a colourless solid is formed after usual working up and column chromatography on 300 ml of silica gel with petrolether (30°-70°C) ethyl acetate 2:1 as the eluting agent: 3,4,5,6-tetra-O-hexanoyl-myo-inositol, m. 120°-122°C.
