Disclosed is a method for the transition metal-mediated oxidation of C—H bonds to form C—O or C—S bonds. The methods are useful for the formation of ethers (R—OR′) from alcohols, R′OH, and sp3-hybridized C—H bonds in substrates, R—H. Aryl or heteroaryl acetates may also be used for C—H to C—OAr bond formation. The methods are also useful in the preparation of C—S bonds from acetyl-protected thiols, MeC(O)SR, and disulfides, RSSR. Advantageously, the methods minimize reaction steps, the handling of oxidized intermediates, and environmental impact.
摘要:
A method for producing a halogenated organic pigment comprising a halogenation step of halogenating an organic pigment with a halogenating agent, wherein the halogenating agent comprises one or more N-haloimide compounds selected from the group consisting of trichloroisocyanuric acid, a metal salt of dichloroisocyanuric acid, tribromoisocyanuric acid, and a metal salt of dibromoisocyanuric acid. According to the present invention, a method for producing a halogenated organic pigment which does not use high toxic raw materials, does not generate a large amount of unfavorable by-products such as hydrogen halide gas and succinimide, and is excellent in terms of safety and productivity can be provided.

摘要:
Vapochromic coordination polymers useful for analyte detection are provided. The vapochromism may be observed by visible color changes, changes in luminescence, and/or spectroscopic changes, for example in the infrared (IR) or Raman signatures. One or more of the above chromatic changes may be relied upon to identify a specific analyte, such as a volatile organic compound or a gas. The chromatic changes may be reversible to allow for successive analysis of different analytes. The coordination polymer has the general formula MW[M′X(Z)Y]N wherein M and M′ are the same or different metals capable of forming a coordinate complex with the Z moiety; Z is selected from the group consisting of halides, pseudohalides, thiolates, alkoxides and amides; W is between 1-6; X and Y are between 1-9; and N is between 1-5. One embodiment provides [Metal(CN)2]-based coordination polymers with vapochromic properties, such as Cu[Au(CN)2]2 and Zn[Au(CN)2]2 polymers.
