Synthesis structure and π-delocalization of a phosphaalkenyl based neutralPNP-pincer

摘要

Graphical abstractA novel bis-phosphaalkenyl based PNP-pincer was prepared and its crystal structure indicates delocalization over the entire π-system including all three donor sites which is also supported by spectroscopic measurements and DFT calculations. The coordination chemistry of the pincer and its precursor have been explored using Cu(I).
