Selection of boron reagents for Suzuki-Miyaura coupling.
Suzuki-Miyaura (SM) cross-coupling is arguably the most widely-applied transition metal catalysed carbon-carbon bond forming reaction to date. Its success originates from a combination of exceptionally mild and functional group tolerant reaction conditions, with a relatively stable, readily prepared and generally environmentally benign organoboron reagent. A variety of such reagents have been d...
متن کاملNOVEL REAGENTS FOR CREATINE KINASE
The purpose of this investigation was to develop a simple colorimetric method for creatine kinase (CK). The new method is based on the reaction of creatine, formed enzymatically from creatine phosphate and ADP, with different glyoxal compounds. Hydrated glyoxals, such as para-nitrophenyl, 2-thiophene, 4- biphenyl, 4, 4' -biphenyl,α-naphthyl, β-naphthyl, para-chlorophenyl, and styryl were...
متن کاملBoron Arylations of Subporphyrins with Aryl Zinc Reagents.
Boron arylations of B-(methoxo)triphenylsubporphyrin have been developed with a combined use of ArZnI⋅LiCl and trimethylsilyl chloride. Aryl zinc reagents bearing bromo, cyano, amide, and ester groups can be employed for the B-arylation reaction to provide the corresponding B-arylated subporphyrins in moderate yields. Postmodifications of B-arylated subporphyrins have been demonstrated without ...
متن کاملReactivity of an oxoboryl complex toward fluorinated aryl boron reagents.
X-Ray and IR data of unprecedented oxoboryl species indicate a significant alteration in the B[triple bond]O bond strength underlining the novel oxoboryl complexes' close relationship with the well investigated and important class of carbonyl complexes.
متن کاملOn methylation of unsaturated acids using boron trihalide-methanol reagents.
Methanolysis of unsaturated fatty acids and triglycerides was carried out with boron trihalide-methanol reagents of various ages. Boron trichloride-methanol produced esters apparently free from contaminants; boron trifluoride caused some loss of highly unsaturated esters after 90 min at 100 or 120 degrees C in Teflon-lined screw-cap vials and at 120 degrees C in ampoules. The losses were more m...
