Structures of S-(pyridin-2-yl) 4-nitro-benzo-thio-ate, S-(pyridin-2-yl) 4-methyl-benzo-thio-ate and S-(pyridin-2-yl) 4-meth-oxy-benzo-thio-ate: building blocks for low-symmetry multifunctional tetra-pyrroles.

ABSTRACT: The crystal structures of three S-(pyridin-2-yl) benzo-thio-esters with varying para-phenyl substituents are presented, namely, S-(pyridin-2-yl) 4-nitro-benzo-thio-ate (1, C₁₂H₈N₂O₃S), S-(pyridin-2-yl) 4-methyl-benzo-thio-ate (2, C₁₃H₁₁NO₂S) and S-(pyridin-2-yl) 4-meth-oxy-benzo-thio-ate (3, C₁₃H₁₁NO₂S). This class of compounds are used in the mono-acyl-ation of pyrrolic species to yield multifunctional tetra-pyrroles. The structures presented herein are the first of their compound class. The dominant inter-actions present in this series are π-π stacking and C-H⋯O inter-actions, and as the para-phenyl motif changes from
