New SCS Pd pincercomplexes featuring a noninnocent indenediide backbone show high catalytic activity in cycloisomerization. A variety of alkylidenelactams (five- to seven-membered rings) have been prepared efficiently from N-tosyl alkynylamides, and good results have also been obtained with challenging alkynoic acids.

Thanks to mechanistic studies, the catalytic performance of SCS indenediide Pd pincer complexes has been spectacularly enhanced using catechol additives as proton shuttles.
