Organocatalytic Synthesis of Substituted Vinylene Carbonates

The organocatalytic synthesis of substituted vinylene carbonates from benzoins and acyloins was studied using diphenyl carbonate as a carbonyl source. A range of N-Heterocyclic Carbene (NHC) precursors were screened and it was found that imidazolium salts were the most active for this transformation. The reaction occurs at 90 °C under solvent-free conditions. A wide range of substituted vinylene carbonates (symmetrical and unsymmetrical, aromatic or aliphatic), including some derived from natural products, were prepared with 20–99% isolated yields (24 examples). The reaction was also developed using thermomorphic polyethylene-supported organocatalysts as recoverable and recyclable species. The use of such species facilitates the workup and allows the synthesis of vinylene carbonates on the preparative scale (>30 g after 5 runs). (Figure presented.).

NOVEL COMPOUND, PHOTOPOLYMERIZATION INITIATOR COMPRISING SAID COMPOUND, AND PHOTOSENSITIVE RESIN COMPOSITION CONTAINING SAID PHOTOPOLYMERIZATION INITIATOR

The purpose of the present invention is to provide: a novel compound which can generate a base and radical upon the irradiation with an active energy ray; a photopolymerization initiator which comprises the novel compound; and a photosensitive resin composition which contains the photopolymerization initiator, has high sensitivity and excellent storage stability, and can be formed into a cured article that does not have a metal-corrosive property. The novel compound is represented by formula (1): (wherein R1 to R6 independently represent a hydrogen atom, a hydroxy group, an alkoxy group, an organic group other than the aforementioned substituents, or the like; X represents a residue having a structure such that n hydrogen atoms are removed from a saturated hydrocarbon containing a ring structure; and n represents an integer of 1 to 6).

(±)Methanodibenzodiazocine tethered [C-H]δ+ functional site: Study towards benzoin condensation and Baylis-Hillman reactions

Abstract New heterocyclic ring systems consisting of (±) methanodibenzodiazocine and imidazolium/ benzimidazolium salts were synthesized in very good yield. Subsequently, these halide salts were subjected to the anion exchange reaction with KPF6 to yield the corresponding azolium salts in excellent yield. The possible applications of these newly prepared salts were investigated in homogeneous catalysis. Remarkable changes in the catalytic activity were observed by varying the bulkiness of N-substituent at imidazole. Catalytic activity of these newly prepared salts was tested for the benzoin condensation reaction. Exclusive formation of benzoin products were observed in good yield. Similarly, the dimerization of cyclohexen-1-one to Baylis-Hillman type product, 2-(3-oxocyclohexyl)-2-cyclohexen-1-one was studied. [Figure not available: see fulltext.]
