Abstract: A method (M1) for the stereo- and regio-selective polymerisation of racemic alkoxides in presence of a polyol activated with a bimetallic mu - oxoalkoxide to give polyether-polyols with an isotactic triad content of more than 25% and a regio-irregularity of less than 50%, involves carrying out the polymerisation in presence of a tert. amine. Independent claims are also included for (1) a method (M2) for the production of polyols activated with mu -oxo-alkoxides by reacting a trialkoxyaluminum compound and a magnesium salt with the polyol in a one-pot reaction without isolating the intermediate mu -oxoalkoxide (2) a method (M3) for the production of such activated polyols by reacting a trialkylaluminum compound with a Mg salt and then reacting the product with the polyol.

Abstract: A catalytically active composition comprises at least one Group 8 metal and at least one cyclic polyether polyol. A catalytically active composition (I) comprises at least one Group 8 metal and at least one cyclic polyether polyol of formula (1). R = H, alkyl, cycloalkyl, aryl or heteroaryl; R = H, alkyl, cycloalkyl, aryl, heteroaryl, WOR , WCOOR , WSO3R , WNE E , (CHR CH2O)xR or W-halogen; W = a single bond or a 1-20 divalent bridging group; R , E , E = H, alkyl, cycloalkyl or aryl; R = H, methyl or ethyl; x = 1-20; X , X = H, polyalkylene oxide or polyalkyleneimine having 1-20 alkylene oxide or alkylene imine units provided that at least one of X and X is a polyalkylene oxide or polyalkyleneimine; n = 4-12. An Independent claim is also included for the production of carbon-carbon and/or carbon-hydrogen (coupled) products using the composition (I).
