Zhu, Diya published the artcileAddition reactions and diazomethane capture by the intramolecular P-O-B FLP: tBu2POBcat, Recommanded Product: Dimesitylphosphine oxide, the publication is Dalton Transactions (2020), 49(3), 901-910, database is CAplus and MEDLINE.
FLPs, R2POBcat (R = tBu 1, Mes 2), are readily derived from the reactions of the corresponding phosphine oxides, BuLi and ClBcat. Despite the poor Lewis acidity of B, these species react with PhOH, CO2, CS2, PhNCO, MesCNO, O2, 9,10-phenanthrenedione, and diazomethanes to effect FLP addition reactions affording heterocycles. The reaction of 1 with EtO2CCHN2 gives the bicyclic product, EtO2CCHN2(tBu2POBcat)2. High-level DFT calculations reveal that these cyclization processes proceed via 1,1-addition to the terminal N of diazomethane followed by 1,2-B-migration affording the five membered rings. The reaction of the EtO2CCHN2 derivative with the 2nd equivalent of FLP 1 is attributed to less steric demands.
