$\mathrm{C}\mathrm{O}\mathrm{O}\mathrm{H}-\mathrm{C}\mathrm{O}\mathrm{O}\mathrm{H}$

$\begin{array}{l}\text{COCl}\\ \text{|}\\ \text{COCl}\end{array}$

${\mathrm{C}}_6{\mathrm{H}}_5-\mathrm{S}{\mathrm{O}}_2-\mathrm{C}\mathrm{l}$

${\mathrm{C}}_6{\mathrm{H}}_5-\mathrm{C}\mathrm{O}-\mathrm{C}\mathrm{l}$
