A method of preparing a compound of the general formula:
in which:
R' and R2 independently represent a hydrogen atom, an alkyl or substituted alkyl group, an aryl or substituted aryl group, an aralkyl or substituted aralkyl group, a cycloaliphatic or substituted cycloaliphatic group or a heterocyclic orsubsti- tuted heterocyclic group providing R' and R2 do not both represent cyclic groups of aromatic nature, or R' and R2 together may represent the necessary atoms to complete a non-aromatic heterocyclic ring,
R3, R4, R5 and R6 independently represent a hydrogen atom or any substituent providing the sum of their 8p constants has a value of less than +0.5. or R3 and R4 and/or R5 and R6 may represent the necessary atoms to complete an alicyclic or aromatic ring, R3 and R2 and/or R' and R6 may represent the necessary atoms to complete a non-aromatic heterocyclic ring,
R7 and R9 independently represent a hydrogen atom or any carbon linked substituent containing up to 16 carbon atoms,
R8 and R10 independently represent a hydrogen atom, an alkyl group having 1 to 4 carbon atoms or any two adjacent substituents R7, R8, R9 and R10 together may complete an alicyclic or aromatic ring, and
X- represents an anion, comprising reacting an amine of the general formula:
in which R1 to R8 are as defined above, with a thiopyrylium salt of the general formula:
in which X- and R7 to R10 are as defined above, to yield the desired compound.
The compounds of formula (I), many of which are new, are useful as sensitizers or photoconductors.
