was obtained. Compounds 1–5 were used for the chemical conversion of glycerol to α-hydroxy acid glyceryl esters by alcoholysis of L-lactide (L-LA), glycolide (GA), and ε-caprolactone (ε-CL). Compounds 1–5 were also efficient initiators for the ring-opening polymerization (ROP) of L-LA, GA, and ε-CL using glycerol as a branching agent to synthesize 3-arm polyesters. Heterometallic compounds 3 and 4 were
在这项工作中,第 13 族金属芳氧化物 [Al(MesalO) 3 ] ( 1 )、[Me 2 Ga(MesalO)] 2 ( 2 )、[AlLi 3 (MesalO) 6 ] ( 3 ) 和 [Me 2 GaLi(MesalO) ) 2 (THF)] ( 4 ) 通过水杨酸甲酯 (MesalOH) 与第 13 族烷基 MMe 3(对于 M = Al、Ga)或它们与 BuLi 在 THF/醇溶液中的组合反应获得。MMe 3 (对于 M = Al, Ga) 和 MesalOH (1 : 3) 直接反应生成化合物1或2, 分别。当用额外的BuLi进行相同的反应时,得到杂金属化合物3或4和[Li 6 (MesalO) 6 ] ( 5 )的混合物。化合物1-5用于通过L-丙交酯 ( L -LA)、乙交酯 (GA) 和 ε-己内酯 (ε-CL)的醇解将甘油化学转化为 α-羟基酸甘油酯。化合物1-5也是
