Activation of phosphorus by group 14 elements in low oxidation states

摘要: The activation of phosphorus remains a popular and competitive area research driven by the dual goals finding ways to avoid environmentally questionable P–Cl compounds applied in many industrial processes target catalytic functionalization P4. In recent years activation, degradation, fragmentation, white with heavier main group elements have become fertile research. isolation various carbenes functionalized silylenes has prompted chemists investigate their reactions phosphorus. most intriguing fact these is subtle change substituents may afford strikingly different compounds. For example, from reaction P4 PhC(NtBu)2SiCl cyclic Si2P2 derivative obtained, whereas analogous PhC(NtBu)2SiN(SiMe3)2 resulted an acyclic Si2P4 framework. Similar phenomena also been observed carbene mediated activation. Apart these, new entry point into chemistry gentle alkyne analogue tin. this feature article we covered low valent 14 special concern developments topic.
