Preparation and Properties of, and Reactions with, Metal-Containing Heterocycles, XXXII1). The Reactive Behavior of [(OC)4Mn - S = PR2]2 Towards IsothiocyanatesBy cleavage of an Mn - S bond and CO elimination the action of the isothiocyanates R' - N = C = S (R' = CH3, C2H5, C6H5) on the dimanganacyclohexadienes [(OC)4Mn - S = PR2]2 (1a, b) [R = CH3 (a), C6H5 (b)] results in the formation of the novel tricyclic compounds (2ax - z, bx - z), in which all three atoms of the heterocumulene have entered into additional bonds. 2ax - z, bx - z are stable towards elevated CO pressure. According to an X-ray structural determination, 2az is present as an enantiomeric mixture and crystallizes in the triclinic space group P1 with Z = 2.
Notes:
Bei der Einwirkung der Isothiocyanate R' - N = C = S (R' = CH3, C2H5, C6H5) auf die Dimanganacyclohexadiene [(OC)4Mn - S = PR2]2 (1a, b) [R = CH3 (a), C6H5 (b)] erhält man durch Öffnung einer Mn - S-Bindung unter CO-Eliminierung die neuartigen, tricyclischen Verbindungen (2ax - z, bx - z), in denen alle drei Atome des Heterocumulens zusätzliche Bindungen eingegangen sind. 2ax - z, bx - z sind gegenüber erhöhtem CO-Druck stabil. Nach einer Kristallstrukturbestimmung liegt 2az als Enantiomerengemisch vor und kristallisiert in der triklinen Raumgruppe P1 mit Z = 2.
