Synthesis and structure of 1,2-[Mo"2R"2(η^2-Bu^tNCR)"4] (R CH"2SiMe"3): insertion of Bu^tNC into dimolybdenum alkyl bonds without rupture of the metal-metal triple bond
The dimolybdenum hexa-alkyl compound [Mo"2(CH"2 SiMe"3)"6] reacts rapidly with >=four equivalents of Bu^tNC in hydrocarbon solvents to produce the η^2-iminoacyl compound 1,2-[Mo"2R"2(η^2-Bu^tNCR)"4] (1; R CH"2SiMe"3). The solid-state structure of 1 co...

| 520 | |a The dimolybdenum hexa-alkyl compound [Mo"2(CH"2 SiMe"3)"6] reacts rapidly with >=four equivalents of Bu^tNC in hydrocarbon solvents to produce the η^2-iminoacyl compound 1,2-[Mo"2R"2(η^2-Bu^tNCR)"4] (1; R CH"2SiMe"3). The solid-state structure of 1 consists of two five-coordinate molybdenum atoms connected by an unbridged metal-metal triple bond, d(MoMo) 2.2581(8) Å. Each molybdenum atom is bonded to the carbon and nitrogen atoms of two iminoacyl groups as well as the carbon atom of an MoCH"2 SiMe"3 group. The environment about each metal centre is best described as pentagonal planar with the iminoacyl carbon atoms mutually cis. The spectroscopic data of 1 indicate that the iminoacyl groups remain η^2-bound in solution, while metal-metal bond rotation is facile. Compound 1 does not react further with Bu^tNC or CO (1 atm) at 25^oC, but at temperatures above 50^oC the compound undergoes thermolysis to produce unidentified products. | ||

Synthesis and structure of 1,2-[Mo"2R"2(η^2-Bu^tNCR)"4] (R CH"2SiMe"3): insertion of Bu^tNC into dimolybdenum alkyl bonds without rupture of the metal-metal triple bond |
| abstract |
The dimolybdenum hexa-alkyl compound [Mo"2(CH"2 SiMe"3)"6] reacts rapidly with >=four equivalents of Bu^tNC in hydrocarbon solvents to produce the η^2-iminoacyl compound 1,2-[Mo"2R"2(η^2-Bu^tNCR)"4] (1; R CH"2SiMe"3). The solid-state structure of 1 consists of two five-coordinate molybdenum atoms connected by an unbridged metal-metal triple bond, d(MoMo) 2.2581(8) Å. Each molybdenum atom is bonded to the carbon and nitrogen atoms of two iminoacyl groups as well as the carbon atom of an MoCH"2 SiMe"3 group. The environment about each metal centre is best described as pentagonal planar with the iminoacyl carbon atoms mutually cis. The spectroscopic data of 1 indicate that the iminoacyl groups remain η^2-bound in solution, while metal-metal bond rotation is facile. Compound 1 does not react further with Bu^tNC or CO (1 atm) at 25^oC, but at temperatures above 50^oC the compound undergoes thermolysis to produce unidentified products. |

The dimolybdenum hexa-alkyl compound [Mo"2(CH"2 SiMe"3)"6] reacts rapidly with >=four equivalents of Bu^tNC in hydrocarbon solvents to produce the η^2-iminoacyl compound 1,2-[Mo"2R"2(η^2-Bu^tNCR)"4] (1; R CH"2SiMe"3). The solid-state structure of 1 consists of two five-coordinate molybdenum atoms connected by an unbridged metal-metal triple bond, d(MoMo) 2.2581(8) Å. Each molybdenum atom is bonded to the carbon and nitrogen atoms of two iminoacyl groups as well as the carbon atom of an MoCH"2 SiMe"3 group. The environment about each metal centre is best described as pentagonal planar with the iminoacyl carbon atoms mutually cis. The spectroscopic data of 1 indicate that the iminoacyl groups remain η^2-bound in solution, while metal-metal bond rotation is facile. Compound 1 does not react further with Bu^tNC or CO (1 atm) at 25^oC, but at temperatures above 50^oC the compound undergoes thermolysis to produce unidentified products. |
