Abstract
Bis-quaternary salts of the formula <FORM:0651433/IV (b)/1> where R1, R2 and R3 are the same or different alkyl groups containing not more than five carbon atoms (or R1 and R2 form a ring with the nitrogen atom, e.g. a piperidine or morpholine ring), A and B are alkyl (of not more than seven carbon atoms), aryl or aralkyl radicals, M is a divalent ion such as SO4 or two monovalent ions such as Cl so that the salt is water-soluble, and the rings C and D and any aromatic portions of A and B may bear alkoxy or alkyl substituents, are prepared by treating with an alkyl ester a compound of the formula <FORM:0651433/IV (b)/2> where A, B, R1 and R2 are as above, except that R1 and/or R2 may be hydrogen. The reaction is usually carried out in a mutual neutral solvent such as methyl alcohol, and, if R1 and/or R2 is hydrogen, an acid-binding agent such as sodium carbonate is added. Methyl iodide is the preferred alkylating agent. Examples are given. Basic ethers of the formula II are obtained from ketones of the formula <FORM:0651433/IV (b)/3> as described in Specification 651,445, e.g. by reduction of the dioximes, further examples being included. 4 : 41-Dibenzoyl-diphenylether is prepared by condensing diphenyl ether with benzoyl chloride in the presence of aluminium chloride. The provisional Specification is not limited as regards the number of carbon atoms in A, B, R1, R2 and R3.
