A. Orita et al., Integrated chemical process. Convergent strategy for ortho-phenylene ethynylene skeleton by one-pot double elimination method, SYNLETT, (9), 2000, pp. 1333-1335
Convergent strategies for ortho-phenylene ethynylene skeletons are realized
on the basis of one-pot double elimination method. This protocol overcomes
unavoidable difficulties encountered in Sonogashira coupling.
