Method for the synthesis of 1,3,5-triarylbenzene derivatives and truxene

• Summary:

  The invention provides a process for manufacturing the derivatives of 1,3,5-triarylbenzene and truxene using aromatic ketones, characterised in that the aromatic ketone is subjected to aldol condensation reaction using an alkyl ester of orthosilicic acid having a general formula Si(Oalkyl)4, wherein alkyl represents the group CnH2n+1, where n = 1 - 10, as well as inorganic or organic non-carboxylic acid as a condensation agent, in an aprotic organic solvent, to yield derivatives of 1,3,5-triarylbenzene, whereas the aromatic group can be phenyl (optionally substituted with R group), pyrenyl, fluoranthenyl, triphenylenyl, and R represents hydrogen, alkyl, chloro, bromo, iodo or nitro group, or to yield derivatives of truxene, unsubstituted or functionalised with alkyl, chloro, bromo, iodo, or nitro group, being the derivatives of 1,3,5-triarylbenzene with a CH2 bridge.
