Abstract
Abstract In the diphenylmethane series, the synthesis of 2,2′ - diiododiphenylmethane ( 4g ) and the improved synthesis of 2,2′ - dibromodiphenylmethane ( 4e ) are reported. The triphenylmethane derivatives, 2-bromo-, 2-iodo-, 2,2′-dichloro-, 2,2′-dibromo- and 2,2′-diiodotriphenylmethane ( 4f, 4h, 4i, 4j and 4k , respectively) have been prepared. Via an entirely different approach, 1-(2-bromophenyl)- and 1 - (2 - chlorophenyl) - 1 - phenyl - 2,2 - dimethylpropane ( 4m and 4l ) were obtained as derivatives of t-butyldiphenylmethane. Examples are given for the application of the new compounds in the synthesis of 9,10 - dihydro - 9 - heteroanthracenes ( 1, 2 and 3 ) via the formation of the corresponding organometallic derivatives.
