Abstract

The construction of CspÀACHTUNGTRENNUNG (aryl) Csp2 bonds is an important transformation in organic chemistry. The resulting aryl alkynes are building blocks often encountered within natural products, pharmaceutical products, and molecular materials.[1] Due to the highly conjugated π system, this structural motif is found in organic semiconductors, and the respective products act as molecular sensors, light-emitting ...
