New routes to diarsenes and arsaphosphenes involving fluorinated arsines

The stable diarsene ArAs=AsAr (1) and arsaphosphene ArAs=PAr (6) (Ar=2,4,6-tri-tert-butylphenyl) have been synthesized in excellent yields from the difluoroarsine ArAsF2 by reaction with ArAs(Li)SiMe3 (for 1) and with ArP(H)Li follow

Reactivity Studies on Metal-Functionalized Phosphaarsenes and the Diarsene Aryl-As=As-Aryl (Aryl = 2,4,6-tBuC6H2) Three-Membered Heterocycles Containing Arsenic Atoms

The transition-metal-functionalized thiaphospharsiranes (2a), (2b), and (2c) are obtained from the reaction of (ν5-C5Me5)(CO)2(PPh3)Fe-As=P-Aryl (1a) and (ν5-C5Me5)(CO)2Fe-E1=E2-Aryl (1b: E1 = As; E2 = P; 1c: E1 = P, E2 = As) with an equivalent amount of sulfur.Further treatment of 2c with sulfur leads to the thiaphospharsirane P-sulfide (6).The heterocycles (13) and (15) are generated from the diarsene Aryl-As=As-Aryl (12) and sulfur or diazomethane, respectively.Structure elucidation of 2a-c, 6, 13, and 15 is based on spectroscopy (IR, 1H, 13C, 31P NMR and MS). - Key Words: Phosphaarsenes/ Diarsenes/ Thiaphospharsiranes/ Thiadiarsiranes/ Diarsiranes
