Lithium-promoted hydroboration of alkynes and alkenes using commercially available hexamethyldisilazane lithium as a precatalyst HBpin hydride source has been developed. This method will be appealing for organic synthesis because its remarkable substrate tolerance good yields. Mechanistic studies revealed that the proceeds through in situ-formed BH3 species, which acts to drive turnover alkenes.

Abstract Heteroaryl boronic acids and esters are extremely important valuable intermediates because of their wide application in the synthesis marketed drugs bioactive compounds. Over last couple decades, construction highly heteroaryl carbon‐boron bonds has created huge attention. The transition‐metal‐free protocols more green, less sensitive to air moisture, also economically advantageous over transition‐metal‐based protocols. C−H borylation heteroarenes C−X (X=halogen) halides represents an excellent approach for synthesis. Also, various cyclization alkyne activation have been recently established goal this review article is summarize existing literature current state art acid esters.

Aryl chlorides as substrates for arylations present a particular challenge photoredox catalytic activation due to their strong C(sp2 )-Cl bond and reduction potential. Electron-rich N-phenylphenothiazines, organophotoredox catalysts, are capable of cleaving aryl simply by photoinduced electron transfer without the need an additional electrochemical setup or any other advanced photocatalysis technique. Due extremely potential in excited state N-phenylphenothiazines substrate scope is high includes both with electron-withdrawing electron-donating substituents. We evidence this reactivity photocatalytic borylations phosphonylations. Advanced time-resolved transient absorption spectroscopy combination electrochemistry was key elucidating comparing unusual photophysical properties not only but also cation radicals central intermediates cycle. The revealed photophysics allowed excited-state radical-cation be fine-tuned molecular design N-phenylphenothiazines; improved activity.
