    Description / Table of Contents: Benzazoles. XXX. Amidomethylation of Aromatic Compounds with 1,3-Bis-chloromethyl-benzimidazolone and 1,3-Bis-chloromethyl-benzimidazolthioneAromatic hydrocarbons are amidomethylated on treatment with 1,3-bis-chloromethyl-benzimidazolone 3 or 1,3-bis-chloromethyl-benzimidazolthione 4 in the presence of aluminium chloride, to give 1,3-bis-arylmethyl-benzimidazolones 5-6 and 1,3-bis-arylmethyl-benzimidazolthiones 7-9, respectively. The amidomethylation of sodium phenates or potassium phenates with 3 and 4 leads to the 1,3-bis-aryloxymethyl-benzimidazolones 10-12 or to the corresponding benzimidazolthiones 13-16 which may be used for the characterization of phenols.
    Notes: Aromatische Kohlenwasserstoffe lassen sich mit 1.3-Bis-chlormethyl-benzimidazolon 3 und mit 1.3-Bis-chlormethyl-benzimidazolthion 4 bei Gegenwart von Aluminiumchlorid zu 1.3-Bis-arylmethyl-benzimidazolonen 5-6 bzw. zu 1.3-Bis-arylmethyl-benzimidazolthionen 7-9 amidomethylieren. Die Amidomethylierung von Natrium- oder Kalium-phenolaten mit 3 und 4 führt zu den 1.3-Bis-aryloxymethyl-benzimidazolonen 10-12 bzw. zu entsprechenden Benzimidazolthionen 13-16, die zur Charakterisierung der Phenole geeignet sind.
