In the presence of a nickel catalyst prepared from Ni(acac)2 and DIBALH (1/1) in situ, three-component coupling reaction of allyl chlorides, 1-alkynes, and alkynyltins yielded regio- and stereoselective 3,6-dien-1-ynes in THF.

A Pd-catalyzed regio- and stereoselective alkynylallylation of a specific C?C σ bond in cyclopropenes, using allyl propiolates as both allylation and alkynylation reagents, has been achieved for the first time. By merging selective C(sp2)-C(sp3) bond scission with conjunctive cross-couplings, this decarboxylative reorganization reaction features fascinating atom and step economy and provides an efficient approach to highly functionalized dienynes from readily available substrates. Without further optimization, gram-scale products can be easily obtained by such a simple, neutral, and low-cost catalytic system with high TONs. DFT calculations afford a rationale toward the formation of the products and indicate that the selective insertion of the double bond of cyclopropenes into the C-Pd bond of ambidentate Pd complex and the subsequent nonclassical β-C elimination promoted by 1,4-palladium migration are critical for the success of the reaction.
A Copper(I)-Mediated Tandem Three-Component Synthesis of 5-Allyl-1,2,3-triazoles
Dutta, Palash,Lee, Soyun,Ryu, Jae-Sang,Song, Yoona
, p. 744 - 754 (2020/02/25)
A copper(I)-mediated tandem three-component reaction using alkynes, azides, allyl iodides, CuI and NaNH 2 is developed. The reactions proceed smoothly at room temperature to afford 5-allyl-1,2,3-triazoles, which can be further converted into 1,2,3-triazole-fused tricyclic scaffolds. This method features an efficient one-pot cascade route using commercial alkynes and affords the corresponding 5-allyl-1,2,3-triazoles with high yields and good selectivity under mild reaction conditions.
Synthesis of aryl allyl alkynes via reaction with allyl amine and aryl alkynoic acids through decarboxylation
Lee, Jieun,Nam, Kye Chun,Lee, Sunwoo
, p. 1008 - 1015 (2020/03/04)
Allyl alkynoic esters were synthesized by the reaction of allyl amines and alkynoic acids via deaminative esterification. The reaction of allyl alkynoic esters with Pd(dba)2 and Xantphos in digylme at 110 °C for 12 h afforded the desired decarb
