Abstract: A process for the preparation of an 1,1-disubstituted oxirane is disclosed, wherein an organic sulphide is reacted in a polar solvent with an educt containing a leaving group attached to a primary or secondary carbon atom, and/or the sulfonium salt formed in this way is reacted with a ketone in presence of a base and a polar solvent. Oxiranes of the type obtained may be further converted into the corresponding ±-hydroxyketone or ±-aminoketone, either in one step by subjecting to aerobic oxidation in the presence of a transition metal catalyst, or in two steps by hydrolyzation in the presence of an aqueous acid to the corresponding dialcohol and subsequent selective oxidation. Further described are some novel epoxide intermediates. The ±-hydroxyketones and ±-aminoketones thus obtainable are useful inter alia as photoinitiators.

Abstract: A process for the preparation of bis-acylphosphanes of formula R1P(COR2)2 wherein R1 is unsubstituted phenyl or phenyl substituted by one to five halogen, C1-C8-alkyl, C1-C8-alkylthio and/or C1-C8-alkoxy; R2 is C1-C18-alkyl or C2-C18-alkenyl; C1-C18-alkyl or C2-C18-alkenyl substituted once or more than once by halogen -OR10, -OCO-R10, -OCO-Hal, -COO-R10, -N(R11)-CO-R10, -N(R11)-CO-Hal, -CO-NR11R10, -CH-CH-CO-OR10 or -CH-CH-phenyl; -C(C1-C4alkyl)=C(C1-C4alkyl)-CO-OR10 or -C(C1-C4alkyl)=C(C1-C4alkyl)-phenyl; C5-C12cycloalkyl, C2-C18alkenyl, phenyl-C1-C4alkenyl, phenyl, naphthyl, biphenyl or a 5- or 6-membered -O-, S- or N-containing heterocyclic ring, the radicals phenyl, naphthyl, biphenyl or the 5- or 6-membered -0-, S- or N-containing heterocyclic ring being unsubstituted or substituted by one to five halogen, C1-C8alkyl, C1-C8alkoxy and/or C1-C8alkylthio; the process comprises the steps in a) selective reduction of dichlorophenylphosphanes of the formula R1P(CI)2 by means of hydrogen at a temperature in the range from 20 to 200° C. and under hydrogen pressure of atmospheric pressure to 20 bar in the presence of a hydrogenation catalyst, a tert. aliphatic amine or an aromatic amine and in the presence of a non protic solvent which is unreactive under the hydrogenation conditions to obtain cyclic phenylphosphanes (R1P)n (n=4 to 6); or b) selective reduction of R1P(CI)2 by means of hydrogen at a temperature in the range from 80 to 250° C. and under hydrogen pressure of 25 to 250 bar in the presence of a hydrogenation catalyst, a tert. aliphatic amine or an aromatic amine and in the presence of a non protic solvent which is unreactive under the hydrogenation conditions to obtain R1PH2; c) subsequent reaction with an acid halide of formula in the presence of an apropriate base R2COHal wherein R2 is as defined above.
