Notes:
Reactions of the Hydrazide-Bridged Clusters HRu3(CO)9(RN - NR2) with AlkynesThe clusters HRu3(CO)9(RN - NR2) (1) with triply bridging hydrazide ligands (RN - NR2 = MeN - NHMe, HN - NHMe, HN - NMe2) undergo reactions with the alkynes HCCPh and PhCCPh to yield three cluster products in each case. One of them (2) is presumed to result from Ru - H insertion with concomitant cluster opening. The second (3) contains an open Ru3 cluster bridged by a unique μ3-η2-vinyl ligand, as shown by a structure determination. The third (4) represents the expected simple reaction product with a s̰,-bound vinyl ligand, again proved by a structure determination. Cluster type 3 is converted to cluster type 2 by CO addition.
