  this paper, we have developed photocatalyst-free and visible light-driven decarboxylative alkylation of pyridinaldehydes. The photochemical reactions are initiated via photoinduced single electron transfer from triethylamine to N-hydroxyphthalimide esters in electron donor–acceptor complexes. This photochemical method can achieve to translate 15 pyridinaldehydes and 11 2-quinolinaldehydes to the corresponding

  有一些从广泛使用的醛到相应的酮的合成方法，但是它们涉及与格氏试剂或过渡金属催化剂的多步反应。在本文中，我们开发了无光催化剂和可见光驱动的吡啶醛脱羧烷基化。光化学反应是通过在电子供体-受体复合物中从三乙胺到N-羟基邻苯二甲酰亚胺酯的光诱导单电子转移引发的。这种光化学方法可以实现将15个吡啶醛和11个2-喹啉醛转化为相应的酮。此外，该策略还可以实现另外两种转化，二硫烷转化为芳基硫化物，苯乙烯砜转化为烷基取代的烯烃。

  Reaction of 3-butenyl radicals generated by photolysis of variously substituted Barton esters (both open-chain 1a-d and cyclohexyl 1e-h) with CF2=CCl2 gave a mixture of cyclized products (cyclopentanes 6 and 8 and cyelohexanes 7 and 9) as well as noncyclized products (4 and 5) in various ratios depending on the substitution pattern at the olefinic moiety. The product ratios of [cyclization (6 + 7 + 8 + 9):noncyclization (5)] for 1 with more alkyl substituents on the CC double bond were greater than those for 1 with fewer substituents. The products ratio of [5-exo (6 + 8):6-endo (7 + 9)] was influenced by a steric effect. Photoreaction of Barton ester 2 with CF2-CCl2 gave a mixture of cyclohexanes 16 and 17 as well as noncyclized 14 and 15. Dehydrochlorination of decalins 7g and 7h followed by oxidation of sulfide and [2,3]sigmatropic rearrangement of the allyl sulfoxide gave octahydronaphthalenones 23 and 27, respectively.
