DOI: 10.1016/j.tetlet.2019.02.041

Abstract: Graphical abstract Herein, we report an efficient new method for iodination of terminal alkynes using stoichiometric KI and CuSO4 in acetate buffer that holds promise for further development into a method for radio-iodination. read more here.

DOI: 10.1021/acs.orglett.2c02695

Abstract: A photoredox thioformylation of terminal alkynes using nitromethane as a formyl anion equivalent, thereby leading to the synthesis of (E)-1,2-difunctionalized acrylaldehyde, has been described. The current strategy introduces an adaptable aldehyde function across an alkyne… read more here.

DOI: 10.1039/d0qo00367k

Abstract: We have developed a highly regioselective halothiolation of alkynes under simple and mild conditions. Our halothiolation reagents are readily available alkali metal halides and N-thiosuccinimides. Our transition metal-free system offers good chemical yields for a… read more here.

DOI: 10.3390/molecules28083433

Abstract: Dehydrogenative borylation of terminal alkynes has recently emerged as an atom-economical one-step alternative to traditional alkyne borylation methodologies. Using lithium aminoborohydrides, formed in situ from the corresponding amine-boranes and n-butyllithium, a variety of aromatic and… read more here.
