Abstract: Compounds of the formula (I) or salts thereof in which R1 is carboxyl or a derivative of a carboxyl group, preferably a radical of the formula —CN, —C(?X)—Y—R or —C(?X)-Het, in which X is O, S or NRa or N—NRaRb, Y is O, S, NRc or NRc—NRdRe, R is H, a (subst.) hydrocarbon radical (HR) or acyl, and Het is an aliphatic nitrogen heterocycle, where each of the radicals Ra, Rb, Rc, Rd and Re is as defined for R or a radical of the formula —OR*, where R* is as defined for R, R2 is H or (subst.) HR or a heterocyclic radical, or, if Z=O or S, also an acyl radical, (R3)n are n radicals R3, as defined in claim 1, Z is a group of the formula O or S(O)x, where x=0, 1 or 2, and n is an integer 0, 1, 2, 3 or 4, as safeners for crop plants or useful plants against phytotoxic actions of agrochemicals, preferably as safeners against the action of pesticides, such as herbicides, in these plants.

Abstract: The present invention provides a crystalline, hydroxide containing double metal cyanide (DMC) catalyst of the formulae (I) or (II), M1x[M2(CN)6]yOH.L??(I) M1x[M2(CN)6]y.zM1(OH)q.L (II) wherein M1 represents a metal selected from Zn+2, Fe+2, Ni+2, Mn+2, Co+2, Sn+2, Pb+2, Fe+3, Mo+4, Mo+6, Al+3, V+4, V+5, Sr+2, W+4, W+6, Cu+2 and Cr+3, M+2 represents a metal selected from Fe+2, Fe+3, Co+2, Co+3, Cr+2, Cr+3, Mn+2, Mn+3, Ir+3, Ni+2, Rh+3, Ru+2, V+4 and V+5, L represents an organic ligand and x, y and q are chosen to maintain electroneutrality. Further provided are processes for the production of the inventive DMC catalysts. The crystalline, hydroxide containing DMC catalysts of the present invention may find use in the preparation of polyols, such as polyether polyols.
