The reaction of organotin compounds with derivatives of triarylmethane in CH2Cl2

The reaction of RSnMe₃ with the triarylmethyl salts Ph₃CBF₄, (C₆Cl₅)₃CSbCl₆ and (p-NO₂C₆H₄)₃CBr was studied. It was shown that the reaction of RSnMe₃ (R  CH₃, CH₂CHCH₂, C₁₃H₉ (9-fluorenyl), C₉H₇ (indenyl), PhCC and CN) with Ph₃CBF₄ is an electrophilic substitution process and that Ph₃CR is formed quantitatively. The reactions of PhSnMe₃ with Ph₃CBF₄ and RSnMe₃ (R  CH₃, CH₂CHCH₂, Ph and PhCC) with (C₆Cl₅)₃SbCl₆ are redox processes. (p-NO₂-C₆H₄)₃CBr only reacts with RSnMe₃ when R is a strong electron withdrawing group (R  9-fluorenyl, indenyl and cyclopentadienyl) and (p-NO₂C₆H₄)₃CR and (p-NO₂C₆H₄)₃C^. are formed. It is assumed that the reactions which give (p-NO₂C₆H₄)₃CR and (p-NO₂C₆H₄)₃C^. are independent.
