Isolatable Organophosphorus(III)-Tellurium Heterocycles

A new structural arrangement Te3(RPIII)3 and the first crystal structures of organophosphorus(III)–tellurium heterocycles are presented. The heterocycles can be stabilized and structurally characterized by the appropriate choice of substituents in Tem(PIIIR)n (m=1: n=2, R=OMes* (Mes*=supermesityl or 2,4,6‐tri‐tert‐butylphenyl); n=3, R=adamantyl (Ad); n=4, R=ferrocene (Fc); m=n=3: R=trityl (Trt), Mesor by the installation of a PV2N2 anchor in RPIII[TePV(tBuN)(μ‐NtBu)]2 (R=Ad, tBu). Inorganic beauty: Organophosphorus(III)–tellurium heterocycles (see figure) can be stabilized and structurally characterized by the appropriate choice of substituents in Tem(PIIIR)n (m=1; n=2, R=OMes* (Mes*=supermesityl or 2,4,6‐tri‐tert‐butylphenyl); n=3, R=adamantyl (Ad); n=4, R=ferrocene (Fc); m=n=3: R=trityl (Trt), Mes*), or by the installation of a PV2N2 anchor in RPIII[TePV(tBuN)(μ‐NtBu)]2 (R=Ad, tBu).
