This work describes Ni-catalyzed cross-electrophile coupling of benzyl chloroformate derivatives with aryl iodides that generates a wide range of diaryl methane products. The mild reaction conditions merit the C-O bond radical fragmentation of benzyl chloroformates via halide abstraction or a single electron reduction by a Ni catalyst. This work offers a new substrate type for cross-electrophile couplings.

Paragraph 0103; 0104; 0105; 0106, (2013/03/26)
The present invention relates to colchicine derivatives expressed in chemical formula 1, or to pharmaceutically acceptable salts thereof, to a method for preparing said derivatives, and to a pharmaceutical composition comprising said derivatives. The colchicine derivatives according to the present invention exhibit superior immunomodulatory effects as compared with conventional immunomodulators or colchicines, and therefore can be valuably used as an immunomodulator for modulating an acute or chronic immune response in organ transplantation.
