- Reaktive Arsen-Heterocyclen. III. 3-Arsolene: Synthese und Reaktionen am Arsen
-
3-Arsolenes (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=Ph, Me, t-Bu, R'=H, Me), treatment with sulphur gives sulphides (R=Me, t-Bu), while oxidation with Br2 or SO2Cl2 results in ring cleavage.From chloroarsolene substitution products (R=I, H, SPh, OMe, NMe2) as well as coupling products with As-As, As-O-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. Key words: Arsolene; Zirconocene; Group 6; Ruthenium; Phosphorus

Gas phase pyrolysis (500-600 deg C, 1 s) of 1-phenyl-3-arsolene, 1-phenyl-3-methyl-3-arsolene, and 1-phenyl-3,4-dimethyl-3-arsolene gives polymeric (PhAs)x and its corresponding diene.Upon increasing the temperature, further decomposition to elemental arsenic and a mixture of aromatic hydrocarbons can be observed.If the pyrolysis is carried out with a large excess of butadiene or dimethylbutadiene, significant amounts of phenylarsinidene transfer products are formed.

3-Arsolenes, R1cyclo(AsCH2C(Me)=C(R2)CH2) (R1 = Ph, Me, t-Bu, R2 = H, Me), are obtained in good yield from chloroarsines, R1AsCl2, and zirconocene diene complexes.They react with methyl iodide at room
