Description
Summary:The reactivity of tin(II) catecholate complex CatSn (1) (where Cat = 3,6‐di‐tert‐butylcatecholate dianion) and two o‐amidophenolate complexes DippAPSn (2) and PhAPSn (3) [where DippAP = 4,6‐di‐tert‐butyl‐N‐(2,6‐diisopropylphenyl)amidophenolate; PhAP = 4,6‐di‐tert‐butyl‐N‐(phenyl)amidophenolate dianions] towards different reagents is reported. Products of the insertion of 1 and 2 into the S–S bond of tetramethylthiuram disulfide were obtained and characterised by X‐ray diffraction analyses. The low temperature oxidation of complexes 1 and 2 with 2‐ethoxy‐3,6‐di‐tert‐butylphenoxy radical enabled us to detect formation of paramagnetic tin(II) derivatives containing the radical‐anion form of the redox‐active ligand. The reaction of tin derivative 3 with Ni(CO)4 leads to substitution of one of the CO groups in the latter with the formation of a new bimetallic product. Multiple modes of reactivity for selected stannylenes bearing redox‐active catecholate and o‐amidophenolate ligands towards different reagents are reported.
