Abstract: 2-Amino-3,5-di-(halomethyl)-pyrazines of the general formula I (I) where X is either chlorine or bromine, m and n may each be 0, 1, 2 or 3 and R1 and R2 are each hydrogen or a protective group or may furthermore be bonded to one another, in particular those compounds of the formula I in which m is 1 and n is 2 and/or R1 and R2 together form a phthaloyl radical, are useful intermediates for the pteridine building block of folic acid or folic acid analogs. They are obtained by a method in which a 2-amino-3,5-dimethylpyrazine of the general formula II (II) is treated with a chlorinating or brominating agent and, where R1 and/or R2 are protective groups, these are, if desired, eliminated when the chlorination or bromination is complete.

Abstract: Quaternary ammonium compounds of the formula where R1 and R2 are identical or different and each is H, halogen, phenyl, alkyl, alkoxy or alkylthio, R3 is H or alkyl, hydroxyalkyl, cycloalkyl or aralkyl, R4 and R5 are identical or different and each is alkyl, phenyl, cycloalkyl or aralkyl or R4 and R5 together are a -(CH2)4- bridge, a -(CH2)5- bridge or a -(CH2)2-O-(CH2)2- bridge, R6 is alkyl and X(-) is Cl(-), Br(-), I(-), CH3SO4(-) or C2H5SO4(-), a process for their preparation from Mannich bases of the formula and alkylating agents, and the use of these quaternary ammonium compounds as initiators for the photopolymerization of polymerizable mixtures containing olefinically unsaturated compounds, especially for the preparation of aqueous polymer dispersions or polymer solutions.
