Ferrocenyl substituted carboranes: synthesis and characterisation

The reaction between ethynyl ferrocene and decaborane affords the new ferrocenyl substituted carborane 1-{Fc}-1,2-closo-C2B10H11 1 [Fc=(η5-C5H4)Fe(η5-C 5H5)]. Deboronation of 1 gives K[7-{Fc}-7,8-nido-C2B9H11] 2, and subsequent metallation, using the {Ru(p-cym)} fragment, affords the novel ferroceny...

description The reaction between ethynyl ferrocene and decaborane affords the new ferrocenyl substituted carborane 1-{Fc}-1,2-closo-C2B10H11 1 [Fc=(η5-C5H4)Fe(η5-C 5H5)]. Deboronation of 1 gives K[7-{Fc}-7,8-nido-C2B9H11] 2, and subsequent metallation, using the {Ru(p-cym)} fragment, affords the novel ferrocenyl substituted ruthenacarborane 1-{Fc}-3-(p-cym)-3,1,2-closo-RuC2B9H10 3 (p-cym=1-Me-C4H4-4-iPr). Reaction between bis(methylethynyl)ferrocene and decaborane affords the bis carborane substituted ferrocene 1,1′-{Fc′}-{2-Me-1,2-closo-C2B10H 10}2, 4 [Fc′=(η5-C5H4)Fe(η 5-C5H4)]. Deboronation of 4 results in the formation [HNMe3]2[7,7′-{Fc′}-{7-Me-7,8-nido-C 2B9H10}2], 5, isolated as a syn and anti diastereoisomeric pair. Metallation of 5 affords the trimetallic ruthenacarborane 1,1-{Fc′}-{2-Me-3-(p-cym)-3,1,2-closo-RuC2B9H 9}2 3, as a mixture of syn and anti diastereoisomers. All the new complexes have been fully characterised by multinuclear NMR and micro-analysis, and for compounds 1, 3, 4 and anti-6 by a single crystal X-ray study.
