Cyclization of ortho-(phenylethynyl)benzene diazonium salts containing groups of +C character at the para-position of the phenyl ring proceeds with closure to a pyrazole, but not to a pyridazine as is the case in the presence of neutral or -C groups.
Over the years there has been considerable interest in the nature of the intermediate produced via solvolysis of cyclobutyl systems. Current feeling is that this process is best described by a concerted, symmetry allowed disrotatory ring opening proceeding from the side opposite to the leaving group
