Chiral phase transfer catalysis,e transfer catalysts still remain to be investigated further, in contrast to reac-tions with the use of achiral phase transfer catalysts. Since excellent reviews on the same subject covering the literature up to 1991 have already appeared [1-3], emphasis will be put on more recent work. However, earlier important results will also be mentioned.作者: 乳汁 時(shí)間: 2025-3-23 15:39 作者: Abrade 時(shí)間: 2025-3-23 18:42 作者: 忘川河 時(shí)間: 2025-3-24 00:26

Phase transfer catalyzed reactions under basic conditions,n the majority of reactions, behave as electrophiles. The action of bases on organic molecules can also result in another process, P-elimination. Here abstraction of a proton is connected with the departure of a leaving group from neighboring carbon atom, thus a new bond is formed between these atom作者: 打擊 時(shí)間: 2025-3-28 13:29 作者: 管理員 時(shí)間: 2025-3-28 17:35 作者: Genome 時(shí)間: 2025-3-28 20:34
