The synthesis and characterization of seven platina-annulenes and their dehydrobenzoannulene (DBA) analogues are reported. Assembly of these macrocycles is accomplished via
Sn transmetalation or amine-mediated oxidative addition with stoichiometric PtCl2(PR3)2,
containing different phosphine ligands, and CuI. In contrast to previously reported DBA
cyclization methodology, incorporation of a doubly σ-bonded Pt complex into the annulene
backbone resulted in selective metallacyclization dependent on competing factors of ligand
identity, PtCl2(PR3)2 isomer, and reaction conditions. Sn transmetalation conditions provided
the most selective metallacyclization control and prevented PtCl2(PR3)2 isomerization during
cyclization.
