英文摘要 | The reaction of (S)-(-)-1,1-diphenyl-propane-1,2-diol with AlCl�迺n diethyl ether furnishes the product [Al((S)-(-)-u �� -OC(H)(Me)C(Ph) �� OH)Cl �� ] �� 1, which decomposes slowly above 25 ℃. Complex 1.2Et �� O crystallizes in the non-centrosymmetric monoclinic space group P2 �� with a=10.591(1)A,b=16.718(1) A, c=12.156(2) A, β=99.30(2), V=2124.1(3) A,z=4.67%,Rw=4.84%, GoF=1.14. The structure of 1 shows a dimer feature, which is hydrogen honded to two diethyl ether molecules. In the reaction of 2-phenoxyethanol with AlMe ��,the dimeric [(u-O(CH �� ) �� OPh) AlMe �� ] �� 2 is obtained in high yield. 2crystallizes in the monoclinic space group P2 �� /c with a=7.398(2)A, b=7.376(2) A, c=20.710(2)A, β =90.56(2), V=1129.9(4)A �� ,z=4,R=5.70%, Rw=7.15%, GoF=1.59. |
