The bis(pentafluorophenyl)borane-catalyzed E-selective isomerization of terminal alkenes to internal alkenes via a hydroboration/retro-hydroboration sequence is reported.
In this Perspective we compare the ability of transition metals and p-block Lewis acids to activate electrophilically hydrosilanes and hydroboranes. The mechanistic similarities and dissimilarities in different catalytic transformations are analyzed.
Isothiocyanates exhibit diverse bioactivities and reactivities. This review describes a comprehensive summary of recent advances in isothiocyanate synthesis with a focus on substrate categorization.
A series of organometallic complexes is reported to demonstrate the versatility in coordination mode of phosphine/sulfoxide carbone. Early and late transition metals can be chelated, in a mono- or bidentate fashion depending on the metal center.
The reactions of methanesulfonic acid and benzenesulfonic acid in binary superacidic systems HF/MF5 (M = As and Sb) were investigated to explore the effects of protonation on the C–S bond and the limits of the protonability of sulfonic acids.
