  3-Arsolenes R-As-CH2-C(Me)=C(R')-CH, (R = Ph, Me, (t)Bu, Cl, R' = H, Me) are readily obtained from zirconocene-butadiene complexes and RAsCl2. Alkylation with methyl iodide gives arsonium salts [R(Me)As-CH2-C(Me)=C(R')-CH2]I (R = Ph, Me, (t)Bu, R'= H, Me), treatment with sulphur gives sulphides R(S)As-CH2-C(Me)=C(Me)-CH, (R = Me, (t)Bu), while oxidation with Br, or SO2Cl2 results in ring cleavage. From chloroarsolene Cl-As-CH2-C(Me)=((Me)-CH2 substitution products R-As-CH2-C(Me)=C(Me)-CH2 (R = 1, H, SPh, OMe, NMe2) as well as coupling products with As-As, As-0-As, and As-S-As units were synthesized. In addition, a number of arsolene complexes with the metals chromium, molybdenum, tungsten, and ruthenium is described.

  Reaction of 2-azidoethyl isocyanide 1, 2-azidophenyl isocyanide 2, or 2-nitrophenyl isocyanide 3 with complexes [Mo(CO)(3)(dppe)(py)] [4] or [W(CO)(3)(dppe)(NE CCH3)] [5] yields the isocyanide complexes [Mo(CO)(3)(dppe)(C NR)] ([6]: C NR = 1; [12]: C NR = 2; [13]: C NR = 3) and [W(CO)(3)(dppe)(C NR)] ([7]: C NR = 1; [14]: C NR = 2; [15]: C NR = 3). Reduction of the nitro or azido groups attached to the isocyanide figands by Zn/NH4Cl (azidoethyl or azidophenyl isocyanides) or Raney-nickel/hydrazine hydrate (nitrophenyl isocyanide) yields exclusively the complexes bearing the 2-amino-functionalized isocyanides. The normally unstable 2-amino-functionalized isocyanides are stabilized by M -> C NR back-bonding, which deactivates the isocyanide carbon atom for an intramolecular nucleophilic attack by the primary amine.
