One thing in common : The formation of binary colloidal semiconductor nanocrystals from single‐ (M(EEPPh 2 ) n ) and dual‐source precursors (metal carboxylates M(OOCR) n and phosphine chalcogenides such as E=PHPh 2 ) is found to proceed through a common mechanism. For CdSe as a model system 31 P NMR spectroscopy and DFT calculations support a reaction mechanism which includes numerous metathesis equilibriums and Se exchange reactions.
