An
efficient electrochemical synthesis of sulfonated
phenanthrenes
via the reaction of internal alkynes with sulfonyl hydrazides has
been established. The protocol does not require a metal catalyst or
external oxidants, providing a green and mild route to functionalized
phenanthrenes. Moreover, the compatibility of various functional groups
and decagram-scale experimental conditions demonstrate the practicality
of the electrochemical strategy.
