Abstract
This review highlights the hydroelementation reactions of conjugated and separated diynes, which depending on the process conditions, catalytic system, as well as the type of reagents, leads to the formation of various products: enynes, dienes, allenes, polymers, or cyclic compounds. The presence of two triple bonds in the diyne structure makes these compounds important reagents but selective product formation is often difficult owing to problems associated with maintaining appropriate reaction regio- and stereoselectivity. Herein we review this topic to gain knowledge on the reactivity of diynes and to systematise the range of information relating to their use in hydroelementation reactions. The review is divided according to the addition of the E-H (E = Mg, B, Al, Si, Ge, Sn, N, P, O, S, Se, Te) bond to the triple bond(s) in the diyne, as well as to the type of the reagent used, and the product formed. Not only are the hydroelementation reactions comprehensively discussed, but the synthetic potential of the obtained products is also presented. The majority of published research is included within this review, illustrating the potential as well as limitations of these processes, with the intent to showcase the power of these transformations and the obtained products in synthesis and materials chemistry.

Abstract
![]()
A formal synthesis
of artemisinin starting from amorphadiene is
described. This new route relies on the development of a catalytic
chemo- and diastereoselective hydrosilylation. The practicability
of this method is demonstrated by converting amorphadiene to dihydroartemisinic
aldehyde using a one-pot hydrosilylation/oxidation sequence, minimizing
the number of purifications and maximizing the productivity through
a practical one-pot procedure. In addition, this approach can be coupled
with a crystallization-induced diastereoselective transformation (CIDT)
to enhance the optical purity of the key target intermediate, dihydroartemisinic
aldehyde.

Abstract
Triphenylborane catalyzes the copolymerization and terpolymerization of epoxides and CO2 to yield polycarbonates with excellent dispersity. Via assisted tandem catalysis, these materials could be hydrosilylated in a one-pot fashion yielding modified polymeric materials. Using only a few reagents, materials with glass transition temperatures ranging from 37-110 °C were obtained.
