Two different terminal alkynes now can be coupled together in the presence of NiCl2·6H2O/CuI by using an excess of one of the terminal alkyne substrates. The new method employed 20 mol % TMEDA as the ligand and environmentally benign O2 or air as the oxidant. It is the first example using Ni-salt as catalyst by employing air or O2 as oxidant, which led to efficient heterocoupling of two different alkynes
现在,可以通过使用过量的一种末端炔烃基质在NiCl 2 ·6H 2 O / CuI存在下将两个不同的末端炔烃偶联在一起。该新方法采用20 mol%的TMEDA作为配体,并采用对环境无害的O 2或空气作为氧化剂。这是第一个使用镍盐作为催化剂,通过使用空气或O 2作为氧化剂的例子,这导致了两个不同炔烃的有效异质偶联。

Lithium alkynyltriisopropoxyborates were homocoupled in the presence of palladium acetate and DPEPhos. This protocol allows a new efficient route to synthesis of 1,3-diynes under very mild conditions.

A novel and efficient Cu(I)-catalyzed oxidative homocoupling of terminalalkynes with diaziridinone as an oxidant is described. Various terminalalkynes can be transformed into the corresponding 1,3-diynes in good yields. The reaction process is base-free, operationally simple, and amenable to the gram scale.

The cobalt catalyzed neutral Diels-Alder reaction of various acyclic1,3-dienes and norbornadiene with 1,3-diynes can be controlled to give the 1:1 adduct, whereas the 1:2 adducts are only formed with sterically less hindered 1,3-dienes. With unsymmetrical 1,3-diynes the regiochemistry is mainly controlled by steric factors for unfunctionalized diynes, whereas the regiodirecting methoxymethyl substituent
