New partially fluorinated epoxides by oxidation of olefins with sodium hypohalites under phase transfer catalysis

Partially fluorinated epoxides can be readily prepared by oxidation of the corresponding olefins by NaOCl (or NaOBr) under phase transfer catalysis (PTC) conditions. Oxidation of CH2=C (CF3)2 at 0-5 °C leads to the formati

Chiral fluorous dialkoxy-diamino zirconium complexes: Synthesis and use in stereospecific polymerization of 1-hexene

New catalysts for the isospecific polymerization of 1-hexene based on cationic zirconium complexes incorporating the tetradentate fluorous dialkoxy-diamino ligands [OC(CF3)2CH2N(Me) (CH2)2N(Me)CH2C(CF3) 2O]2[(ON2NO)2-] and [OC(CF 3)2CH2N(Me)(1R,2R-C6,H 10)N(Me)CH2C(CF3)2O]2- [(ONCyNO)2-] have been developed. The chiral fluorous diamino-diol [(ONCyNO)H2, 2] was prepared by ring-opening of the fluorinated oxirane (CF3)2COCH2 with (R,R)-N,N′-dimethyl-1,2-cyclohexanediamine. Proligand 2 reacts cleanly with [Zr(CH2Ph)4] and [Ti(OiPr)4] precursors to give the corresponding dialkoxy complexes [Zr(CH2Ph) 2(ONCyNO)] (3) and [Ti(OiPr)2(ON CyNO)] (4), respec tively. An X-ray diffraction study revealed that 3 crystallizes as a 1:1 mixture of two diastereomers (Λ-3 and Δ3), both of which adopt a distorted octahedral structure with trans-O, cis-N, and cis-CH2Ph ligands. The two diastereomers Λ-3 and Δ-3 adopt a C2-symmetric structure in toluene solution, as established by NMR spectroscopy. Cationic complexes [Zr(CH2Ph)(ON 2NO)(THF)n]+ (n = 0, anion = [B(C 6F5)4]-, 5; n = 1, anion = [PhCH2B(C6F5)3]-, 6) and [Zr(CH2Ph)(ONCyNO)(THF)]+ [PhCH 2B(C6F5)3]- (7) were generatedfrom the neutral parent precursors [Zr(CH2Ph) 2(ON2NO)] (H) and [Zr(CH2Ph) 2(ONCyNO)] (3), and their possible structures were determined on the basis of 1H, 19F, and 13C NMR spectroscopy and DFT methods. The neutral zirconium complexes H and 3 (Λ3/Δ-3 mixture), when activated with B-(C6F 5)3 or [Ph3C] + [B(C 6F5)4]-, catalyze the polymerization of 1-hexene with overall activities of up to 4500 kg PH mol Zr lh-1, to yield isotactic-enriched (up to 74% mmmm) polymers with low-to-moderate molecular weights (Mw = 4800-47200) and monodisperse molecular-weight distributions (Mw/Mn = 1.17-1.79).

PREPARATION OF 2,2-BIS (FLUOROALKYL) OXIRANE AND PREPARATION OF PHOTOACID GENERATOR THEREFROM

A 2,2-bis(fluoroalkyl)oxirane (A) is prepared by reacting a fluorinated alcohol (1) with a chlorinating, brominating or sulfonylating agent under basic conditions to form an oxirane precursor (2) and subjecting the oxirane precursor to ring closure under basic conditions. R1 and R2 are fluoroalkyl groups, R3 and R4 are hydrogen or monovalent hydrocarbon groups, X is chlorine, bromine or —OSO2R5 group, and R5 is alkyl or aryl.

POLYFLUORINATED EPOXIDES AND ASSOCIATED POLYMERS AND PROCESSES

A method for producing partially fluorinated epoxides and corresponding polyether homopolymers of these polyfluorinated epoxides is described. Also described is a method for incorporating a fluoroalcohol functional group into a polymer as a pendant group. Certain perfluorinated olefins are also described. These polyfluorinated epoxides and the associated polymers and methods relating to them are useful components in photoresists, particulary in lithographic photoresists for use at low ultraviolet wavelengths (e.g., 157 nm).
