Photo[2+2]cycloaddition of olefins is a sought-after tool for making cyclobutanes,which are the building blocks for a wide range of biologically active molecules and natural products.However,the formation of cyclobutane derivatives from aryl terminal olefins is problematic due to their high redox potential,and high energy in the excited state,making visible-light-absorbing photocatalyst difficult to realize either electron or energy transfer to olefins during the photocyclic addition process.Herein,we report,for the first time,the aggregationinduced photo[2+2]cycloaddition of two olefins by visible-light catalysis in homogeneous solution.An array of control experiments and spectroscopic analyses reveal that the terminal olefins tend to aggregate to form excimers/exciplexes,which possess much lower energy than their monomeric forms,and enables triplet energy transfer from excited Ir(ppy)3*to supramolecular self-assembly feasible,leading to homo and cross[2+2]photodimerization of the olefins to fabricate cyclobutanes at ambient conditions in good to excellent yields. 展开更多

Dialkyl-substituted terminal olefins were synthesized from the coupling reaction of a-olefins which were catalyzed by zirconocene dichloride/methylalumoxane (MAO) catalyst system under mild condition. High yield was gained and no other oligmer was detected. It was found that the ratio of AI/Zr is responsible for the selectivity of product. 展开更多
