Tetramethylarsoles (R=Ph, Me, t-Bu) have been obtained from Cp2Zr(C4Me4) and RAsCl2.From these a number of complexes of the type M(CO)5 (arsole) (M=Cr, W), cis-W(CO)4L(arsole) (L=piperidine, i-Pr3P), PF6, PF6 ((PR3)2=(PPh3)2, dppm, dpme), and *RuL2(arsole)>PF6 (L2=(PMe3)2, norbornadiene) have been prepared through ligand exchange reactions.For R=Me, Ph the complexes readily undergo Diels-Alder-addition with acetylenedicarboxylic acid dimethyl ester.The 7-arsanorbornadienes formed as intermediates are unstable and decompose into arene and arsinidene complex which in one case has been trapped through consecutive insertion reactions. Key words: Arsole, Zirconocene; Phosphorus; Manganese; Ruthenium; Group 6
