Formation of a new class of 7π radicals via sterically induced P–P bond cleavage of the dimers [(CH)2(NR)2P]2†
Abstract
The 2c–2e− P–P bonded dimers [(CH)2(NR)2P]2 dissociate in solution to give the persistent new 7π radicals [(CH)2(NR)2P]˙, which are isoelectronic with the well known S/N thiazolyl radicals.
