Abstract
Double insertion of $CS_2$ into two Ru-H bonds of $[(dppm)_2Ru(H)_2] (dppm = Ph_2PCH_2PPh_2)$ affords the methanedithiolate complex $[(dppm)_2Ru( 2-S_2CH_2)]$. The methanedithiolate moiety has been functionalized using 2 equiv of RX resulting in bis(alkylthio)methane derivatives $[(dppm)_2Ru(RSCH_2SR)][X]_2$. The bis(alkylthio)methane complex loses the bis(alkylthio)methane moiety under very mild conditions and in turn affords the $[(dppm)_2RuX\$2]$ complex from which the starting dihydride $[(dppm)_2Ru(H)_2]$ has been regenerated via reaction with KOH/EtOH. On the other hand, insertion of $CS_2$ into one Ru-H bond of $[(dppe)_2Ru(H)_2] (dppe = Ph_2PCH_2CH_2PPh_2)$ followed by functionalization using RX results in alkyl dithioformate complex trans- $[(dppe)_2Ru(H)(SC(SR)H)][X]$. In this case also, the alkyl dithioformate moiety gets eliminated under very mild conditions to afford the $[(dppe)_2Ru(H)(X)]$ derivative from which the starting dihydride has been regenerated via reaction with $NaBH_4$. The reactions presented here constitute utilization of $CS_2$ as a $C_1$ synthetic source for the generation of useful organic compounds.
