Abstract
A metal cyclopentadienyl complex has the formula: wherein m≥0; M is a Group I, II or III main group metal, alkali or transition metal; CHrepresents a Cp ring where two hydrogens are substituted by M and R(F); R(F)is connected to any one of the carbon atoms of the Cp and selected from a hydrocarbyl, fluorohydrocarbyl, silyl group [SiR'], or amino group [—NRR]. The metal cyclopentadienyl complexes include Li(CH-2-CH) (CAS No: 2413046-23-6), K(CH-2-CH), Na(CH-2-CH), K(CH-1-F—CH), K(CH-1,1,1-3F—CH), Li(CH-2-CH), or In(CH-2-CH) (CAS No.: 2364634-67-1). A mono-substituted cyclopentadiene has the formula: wherein m≥0; CHrepresents the Cp ring where one hydrogen is substituted R(F); R(F)is connected to any one of the carbon atoms of the Cp and selected from a hydrocarbyl, fluorohydrocarbyl, silyl group [SiR'], or amino group [—NRR]. The mono-substituted cyclopentadienes include CH-1-F—CH, CH-2-CH, CH-2-CH, or CH-1,1,1-3F—CH.
