摘要：

The activation of alkynes HC=CR with cis-[RuCl2(Ph2PCH2PPh2)2] leads to vinylidenes trans-[(Ph2PCH2PPh2)2(Cl)Ru+=C=CHR], even directly from acetylene itself (R=H) or prop-2-ynyl alcohol, from which the Ru+=C=CH(CH2OH) moiety is resistant to dehydration, and deprotonation with 1,8-diazabicyclo[5.4.0]undec-7-ene (DBU) directly affords trans-[(Ph2PCH2PPh2)2(Cl)Ru-C=C-R] derivatives.
