Unexpected formation of the new oxorhenium (V) complex [ReO(NH(CH2CH2S)2)(SC6H5)] obtained by NC cleavage of the tripodal ligand N(CH2CH2SH)3
摘要:
The tripodal ligand 2,2',2''-nitrilotris(ethanethiol) (N(SH)(3)=N(CH2CH2SH)(3)) reacts with [ReO(SC6H5)(4)](-) as rhenium(V) precursor to give unexpectedly the square-pyramidal oxorhenium(V) species [ReO(NH(CH2CH2S)(2))(SC6H5)] (1). The reaction mechanism is assumed to involve cleavage of the chelate ligand catalysed by the metal core. Treatment of 1 with methyl iodide at room temperature leads to substitution of the thiolate ligand by iodide and methylation of the amine nitrogen to the compound [ReO(NCH3(CH2CH2S)(2))I] (2).
