| Περίληψη | The alkyne complex [Ru(CO) 2 (MeC,CPh)(η 5 -7,8-C 2 B 9 H 11 ] (3c) has been prepared and its structure determined by X-ray crystallography. The ruthenium is co-ordinated on one side by the nido-7,8-C 2 B 9 H 11 fragment in a pentahapto manner, and on the other by the two CO molecules and the alkyne [Ru–C av. =2.305, C–C=1.228(3) Å. Treatment of 3c with PEt 3 and Ph 2 PCH 2 PPh 2 in CH 2 Cl 2 affords the ylid complexes [Ru{C(Me)C(Ph)PEt 3 }(CO) 2 (η 5 -7,8-C 2 B 9 H 11 )] (4b) and [Ru{C(Me)C(Ph)P(Ph) 2 CH 2 PPh 2 }(CO) 2 (η 5 -7,8-C 2 B 9 H 11 )] (4c), respectively. The structure of 4b was established by an X-ray diffraction study which revealed that the PEt 3 molecule was attached to the carbon atom of the CPh group. In contrast, reactions between 3c and the donor molecules AsPh 3 , SbPh 3 and Ph 2 P(S)CH 2 P(S)Ph 2 resulted in displacement of the alkyne and formation of the complexes [Ru(CO) 2 (L)(η 5 -7,8-C 2 B 9 H 11 )] (5a, L=AsPh 3 ; 5b, L=SbPh 3 ; 5c, L=Ph 2 P(S)CH 2 P(S)Ph 2 ). Treatment of 4c with the Ru(CO) 2 (η 5 -7,8-C 2 B 9 H 11 ) fragment yielded the diruthenium complex [Ru 2 (μ-Ph 2 PCH 2 PPh 2 )(CO) 4 (η 5 -7,8-C 2 B 9 H 11 ) 2 ] (6). The structure, based on the linking of two Ru(CO) 2 (η 5 -7,8-C 2 B 9 H 11 ) groups by the ligand Ph 2 PCH 2 PPh 2 , was determined by X-ray crystallography. NMR data for the new complexes are reported. | el |
