Abstract
The reaction of Ru3(CO)12 with 3,3 dimethylthietane (DMT) at 68°C yielded the new tetraruthenium cluster complex Ru4(CO)12(μ-SCH2CMe2CH2)2,1 in 23% yield. Compound1 was characterized crystallographically and was shown to consist of a puckered square of four ruthenium atoms with two DMT ligands bridging opposite sides of the cluster via the sulfur atoms. Compound1 reacts with CO (98°C/1 atm) to yield the new tetraruthenium complex Ru4(CO)13 (μ-SCH2CMe2CH2),2 in 69% yield. Compound2 consists of a butterfly tetrahedral cluster of four ruthenium atoms with a DMT ligand bridging the wing-tip metal atoms. Addition of DMT to2 regenerates1 in 67% yield.
