The polymerization of caprolactone ( 1-CL) was initiated by yttrium triisopropoxide {Y(OP i r ) 3 }, bimetallic isopropoxide of yttrium and aluminum {Y[Al(OP i s ) 4 ] 3 }, yttrium and tin(II) {Y[Sn(OP i r ) 3 ] 3 }, and tin(II) and yttrium {Sn[Y(OP i r ) 4 ] 2 }, respectively. The polymerization wa
The effect of the alkali metal on the synthesis, crystal structure, and catalytic reactivity of lanthanide-alkali metal alkoxide clusters is reported. Anhydrous LnCl 3 reacts with 6.5 equiv. of KOCH 2 CH 2 N(CH 3 ) 2 and 1.5 equiv. of KOH in tetrahydrofuran (THF) to give the corresponding lanthanide
