SALT AND PHOTORESIST COMPOSITION

PROBLEM TO BE SOLVED: To provide a salt in which a focus margin (DOF) and a mask error factor (MEF) of a pattern which is acquired are favorable, and to provide a resist composition containing the salt.SOLUTION: The salt is shown by formula (I), and the resist composition contains the salt. In the formula, Rand Reach denote a hydroxy group or an alkyl group, wherein a methylene group in the alkyl group may be replaced with an oxy group or the like; Rdenotes an alkyl group; l, m and n each denote an integer of 0-3; p denotes an integer of 1-3; a methylene group of a heterocyclic ring containing a sulfonium cation may be replaced with an oxy group or carbonyl group; Rand Reach denote a fluorine atom or a perfluoroalkyl group; Ldenotes a divalent saturated hydrocarbon group, wherein a methylene group in the group may be replaced with an oxy group or a carbonyl group; and Y denotes an aliphatic hydrocarbon group or a saturated cyclic hydrocarbon group, wherein a methylene group in the groups may be replaced with an oxy group or the like.

The Use of Ureates as Activators for Samarium Diiodide

A novel mode of SmI2 activation has been developed using ureates as reaction promoters. Several ureates formed by treatment of the corresponding ureas with n-BuLi have been shown to activate SmI2 to a substantial extent toward the reduction of 1-chlorodecane. Complexes formed from SmI2 and various ureates have been shown to be useful for the reduction of a variety of organohalides, including substrates of low reactivity such as aryl fluorides. Because of ease of synthesis and low molecular weight, the conjugate base of triethylurea (TEU-) was of primary focus. Visible spectroscopy and reactivity data are consistent with the hypothesis that the same complex is being formed when SmI2 is combined with either 2 or 4 equiv of TEU-, in spite of the greater reactivity of SmI2/4 TEU- with some alkyl halides. We propose that the active reductant is an N,O chelate formed between SmI2 and 2 equiv of TEU-.

Microwave-Assisted solid-liquid phase alkylation of naphthols

The microwave promoted alkylation of 1- and 2-naphthols with benzyl, butyl, ethyl and isopropyl halides in the presence of an alkali carbonate may result in O- and C-Alkylated products. The alkylations were O-selective in the presence of K2CO3 in acetonitrile as the solvent and in the absence of phase transfer catalyst. The alkylations utilizing butyl and ethyl halides were also O-selective in solventless accomplishment and in the presence of triethylbenzylammonium chloride.
