The first example of the catalytic asymmetric Mukaiyama–Michael reaction was the reaction of 2-carbomethoxycyclopentanone and 1-TMSO-1-tert-butoxypropene by Scolastico using the combination of Phebox28 and Cu(OTf)2 or Cu(SbF6)2 as the catalyst to give the syn and anti adducts in ratios of ...
22 ORGANIC REACTION MECHANISMS When 2-bromobutane is allowed to react with the methoxide ion in methanol, less than half of the starting material is converted into methyl isopropyl ether; the rest is transformed into 2-propene. Br A CH3CHCH2CH3 ϩ CH3OϪ OA CH3 CH3CHCH2CH3 ϩ CH2PCH...
If an extended electron rich π-system species reacts via a single atomic centre, for example when an allyl anion is protonated to give propene, the species is better considered behaving as an ambidentate, π-stabilised Lobe-HOMO Lewis base. However, when when the species reacts via its ...
