Mono-substituted cyclopentadienes and metal cyclopentadienyl complexes and synthesis methods thereof

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; C5H4 represents a Cp ring where two hydrogens are substituted by M and R(F)m; R(F)m is connected to any one of the carbon atoms of the Cp and selected from a hydrocarbyl, fluorohydrocarbyl, silyl group [SiR′3], or amino group [—NR1R2]. The metal cyclopentadienyl complexes include Li(C5H4-2-C5H11) (CAS No: 2413046-23-6), K(C5H4-2-C5H11), Na(C5H4-2-C5H11), K(C5H4-1-F—C4H10), K(C5H4-1,1,1-3F—C4H6), Li(C5H4-2-C4H9), or In(C5H4-2-C5H11) (CAS No.: 2364634-67-1). A mono-substituted cyclopentadiene has the formula: wherein m≥0; C5H5 represents the Cp ring where one hydrogen is substituted R(F)m; R(F)m is connected to any one of the carbon atoms of the Cp and selected from a hydrocarbyl, fluorohydrocarbyl, silyl group [SiR′3], or amino group [—NR1R2]. The mono-substituted cyclopentadienes include C5H5-1-F—C4H10, C5H5-2-C5H11, C5H5-2-C4H9, or C5H5-1,1,1-3F—C4H6.
