Synthesis of C 1- and C 3ν-Symmetric Porphyrin Trimers Based on Triphenylmethane Cores
摘要:
This work describes the synthesis of a new class of tripodaphyrin derivatives with a triphenylmethane core. Both C-1- and C-3 nu-symmetric tetrahedral large molecules with covalently linked rigid elements were obtained.

A new C−Ge bond-forming framework was established, which bridges a gap between a recently developed mild coupling technique and organogermane chemistry. The method provides a mild approach for the synthesis of both aryl and alkenyl germanes, with improved molecular diversity and structural complexity, using readily available carbon electrophiles and chlorogermanes as starting materials.
