摘要: Abstract Dialkyl (3,4-dicyanophenyl)propargylmalonates were prepared by the reaction of propargyl bromide and potassium salt dialkyl-3,4-dicyanophenylmalonates. A cyclotetramerization was achieved in pentanol presence DBU without protective/deprotective chemistry, affording peripherally tetrasubstituted alkynyl phthalocyanines. Subsequently, situ metallation ‘clicking’ employed for first time as an efficient quantitative route to tetratriazole-functionalized
