SALT, ACID GENERATOR, RESIST COMPOSITION AND METHOD FOR PRODUCING RESIST PATTERN

Disclosed are a salt represented by formula (1), and an acid generator and a resist composition which include the same: wherein R1 represents a fluorine atom or a fluorinated alkyl group; R2, R3 and R4 each represent a halogen atom, a fluorinated alkyl group or a hydrocarbon group; m2 and m3 represent an integer of 0 to 4; m4 represents an integer of 0 to 5; Q1 and Q2 each represent a fluorine atom or a perfluoroalkyl group; L1 represents a saturated hydrocarbon group, —CH2- included in the group may be replaced by —O— or —CO—, and a hydrogen atom included in the group may be substituted with a fluorine atom or a hydroxy group; Y1 represents a methyl group which may have a substituent or an alicyclic hydrocarbon group which may have a substituent.

Atom-efficient transition-metal-free arylation ofN,O-acetals using diarylzinc reagents through Zn/Zn cooperativity

Exploiting the cooperative action of Lewis acid Zn(C6F5)2with diarylzinc reagents, the efficient arylation ofN,O-acetals to access diarylmethylamines is reported. Reactions take place under mild reaction conditions without the need for transtion-metal catalysis. Mechanistic investigations have revealed that Zn(C6F5)2not only acts as a Lewis acid activator, but also enables the regeneration of nucleophilic ZnAr2species, allowing a limiting 50 mol% to be employed.

Vinyl Carbocations Generated under Basic Conditions and Their Intramolecular C-H Insertion Reactions

Here we report the surprising discovery that high-energy vinyl carbocations can be generated under strongly basic conditions, and that they engage in intramolecular sp3 C-H insertion reactions through the catalysis of weakly coordinating anion salts. This approach relies on the unconventional combination of lithium hexamethyldisilazide base and the commercially available catalyst, triphenylmethylium tetrakis(pentafluorophenyl)borate. These reagents form a catalytically active lithium species that enables the application of vinyl cation C-H insertion reactions to heteroatom-containing substrates.
