Substituent effects on the photochromic properties of benzothiophene-based derivatives
Galangau, Olivier,Nakashima, Takuyama,Maurel, Fran?ois,Kawai, Tsuyoshi
supporting information, p. 8471 - 8482 (2015/06/02)
Five diarylethene photochromic derivatives, the structures of which incorporate a central benzothiophene unit, a left-hand thiazole group, and a right-hand benzothiophene group, have been prepared. The compound with a thiazole unit with no substituent on the reaction-center carbon atom reveals an unprecedented transformation upon light irradiation. When the 4-position of thiazole is protected by a methyl group, the compounds show high photosensitivity and photochromic properties. In this case, light irradiation affords new compounds with [5]helicene structures featuring the highest redshifted absorption maxima reported to date.

NaBH4-TMEDA and a palladium catalyst as efficient regio- and chemoselective system for the hydrodehalogenation of halogenated heterocycles
Chelucci, Giorgio,Figus, Susanna
, p. 191 - 209 (2014/07/21)
The pair NaBH4-TMEDA as hydride source and a palladium catalyst in THF prove to be an efficient system for the hydrodehalogenation of halogenated heterocycles with one or more heteroatoms. In general, Pd(OAc) 2-PPh3 rapidly hydrodehalogenates reactive halo-heterocycles such as bromo-pyridines, -quinolines, -thiophenes, -indoles, -imidazoles, etc., at room temperature in very good yields, whereas in most cases PdCl2(dppf) reduces less reactive halides such as chloro-pyridines, -quinolines, -pyrimidines and bromo-indoles, -benzofurans, etc. Moreover, PdCl2(tbpf) shows to be even more active removing the 2- and 5-chlorine from both thiophene and thiazole rings. The reaction conditions tolerate various functional groups, allowing highly chemoselective reactions in the presence of halide, ester, alkyne, alkene and nitrile substituents. Moreover, with a proper selection of the catalyst it is also possible to obtain a good control in the regioselective hydrodehalogenation of a variety of polyhalogenated substrates.

Paragraph 0175, (2013/11/19)
Agri-horticultural pest control compositions having outstanding control effect on pests, in particular, agri-horticultural pests, which comprise as active ingredients one or more 4-(3-butynyl)aminopyrimidine derivatives represented by the general formula [I], namely, where R1 is typically selected from among: a) phenyl c) —SiR5R6R7 (R5, R6, and R7 which may be the same or different represent a linear or branched alkyl having 1-6 carbon atoms, a linear or branched haloalkyl having 1-3 carbon atoms which is substituted by one halogen atom, a linear or branched cyanoalkyl having 1-3 carbon atoms which is substituted by one cyano group, and phenyl); d) hydropgen atom; R2 typically represents a hydrogen atom; R3 typically represents a hydrogen atom; R4 represents a hydrogen atom and one or more agri-horticultural pest control compounds selected from among agri-horticultural antimicrobial compounds, say, multi-site contact active compouns, nucleic acids synthesis inhibitory active compounds, mitosis and cell divesion inhibitory active compounds, and/or agri-horticultural insecticidal, miticidal or nematicidal compounds, say, acetylcholinesterase inhibitors, GABA-gated chloride antagonists, and sodium channel modulators. Since the 4-(3-butynyl)aminopyrimidine derivatives and the existing antimicrobial active compounds and/or insecticidal active compounds are used in admixture, the 4-(3-butynyl)aminopyrimidine derivatives which are useful as pest control agents, particularly as agri-horticultural pest control agents, need be used in smaller amounts and yet their antimicrobial or insecticidal activity can be improved.
