Neutral Fe(iv) alkylidenes, including some that bind dinitrogen

Neutral, formally Fe(iv) alkylidene species are sought as plausible olefin metathesis catalysts, and the synthesis of several is described herein. The complexes are prepared via nucleophilic attack (Nu = MeLi, PhCH2K, 2-picolyllithium, Me2PCH2Li, MePhPCH2Li, Ph2PCH2Li) at the imine of cationic [mer-{κ-C,N,C-(C6H4-yl)-2-CH=N(2-C6H4-C(iPr)=)}Fe(PMe3)3][B(3,5-CF3-C6H3)4]. In contrast, MeMgCl and mesityllithium displaced and deprotonated bound PMe3, respectively. Structural details are provided for mer-{κ-C,N,C-(C6H4-yl)-2-CH(Bn)N(2-C6H4-C(iPr)=)}Fe{trans-(PMe3)2}N2 and {κ-C,N,C,P-(C6H4-yl)-2-CH(CH2PMe2)N(2-C6H4-C(iPr)=)}Fe(PMe3)2.

REACTION OF 2-PICOLYLLITHIUM AND 6-METHYL-2-PICOLYLLITHIUM WITH VINYL(tert-BUTYL)ACETYLENE

The possibility of obtaining pyridylallene hydrocarbons with normal structure with a branched grouping in the side chain on the basis of vinyl(alkyl)acetylene hydrocarbons with iso structures and, respectively, 2-picolyl and 2,6-lutidyllithium is demonstrated.

Synthesis, structure and coordination of the ambiphilic ligand (2-picolyl)BCy2

The new pyridine-borane compound (2-picolyl)BCy2, readily prepared from 2-picolyllithium and ClBCy2, adopts a head-to-tail dimeric structure in the solid state as indicated by X-ray diffraction analysis and according to NMR and DFT studies, the dimeric form equilibrates in solution with a strained monomeric structure; the ambiphilic behavior of the new compound is illustrated by its bridging coordination to the (p-cymene)RuCl2 unit.
