Reaktive Arsen-Heterocyclen. III. 3-Arsolene: Synthese und Reaktionen am Arsen

Article abstract of DOI:10.1016/0022-328X(94)88008-5

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
