The　development　of　general　and　efficient　strategies　for　the　construction　of　allenes　is　important　due　to　their　wide　applications.　Although　few　protocols　have　been　developed　via　the　1,4-difunctionalization　of　1,3-enynes　under　thermal　or　photoredox　conditions,　the　mild　and　robust　methodology　for　dicarbofunctionalization　and　hydroalkylation　remains　unexplored.　In　the　present　study,　we　report　an　electrochemical　multicomponent　protocol　for　the　chemo-　and　regioselective　difunctionalization　of　1,3-enynes.　In　particular,　1,4-arylalkylation　and　unsymmetrical　dialkylation　have　been　realized　via　electro-　and　nickel　dual　catalysis　using　graphite/nickel　foam　and　zinc/nickel　foam　as　electrodes,　respectively.　The　use　of　a　Zn/reticulated　vitreous　carbon　electrode　led　to　efficient　1,4-hydro(deutero)alkylation　in　the　absence　of　a　metal　catalyst.　A　wide　range　of　structurally　diverse　tri-　and　tetra-substituted　allenes　were　easily　prepared　with　good　efficiency　and　excellent　regioselectivity　under　mild　reaction　conditions.　Notably,　a　series　of　natural　product-　and　drug-derived　substrates　could　undergo　late-stage　functionalization　to　generate　the　corresponding　complex　allenes.　The　synthesis　of　allenes　through　1,4-difunctionalization　of　1,3-enynes　typically　requires　preformed　organometallic　species,　high　temperature　or　specific　alkyl　radical　precursors.　Now　an　electrochemical　multicomponent　protocol　for　the　chemo-　and　regioselective　1,4-difunctionalization　of　1,3-enynes　is　reported,　which　uses　alkyl　bromides　with　aryl　bromides,　alkyl　bromides　or　H2O/D2O　as　reagents　for　1,4-difunctionalization.
