    • The invention provides a method of carrying out a Lewis-acid catalysed organic reaction in the presence of a Lewis acid catalyst comprising a metal-organic compound having the following formula: M(HO(CR 1 R 2 )z)a(O(CR 1 R 2 )z)bY-(CR 3 R 4 )χ-Y((CR 1 R 2 )zO)c((CR 1 R 2 )zOH)d.nR 5 OH (Formula I) in which: M is a metal atom, preferably titanium, zirconium, hafnium or iron (III) Y is selected from P and N, but is very preferably N; each R 1 , R 2 , R 3 and R 4 is independently selected from H, alkyl, aryl, substituted alkyl or substituted aryl, R 5 is hydrogen, an alkyl group, a hydroxy-functionalised alkyl group, a polyoxyalkylmoiety, R 6 O or R 7 COO where R 6 and R 7 may each represent H, alkyl, aryl or alkyl-aryl; d and a are each O or 1, b and c are each 1 or 2, b + c = the valency of M, a+b+c+d = 4, each z is independently 1,2, 3 or 4; x represents the least number of C atoms between the Y atoms and is 2 or 3 and n is a number in the range from 0 to 4. The metal-organic compound forms a stable hydrate in water which retains Lewis-acid catalytic properties.
    • 本发明提供一种在路易斯酸催化剂存在下进行路易斯酸催化的有机反应的方法,该路易斯酸催化剂包含具有下式的金属有机化合物:M(HO(CR 1 R 2)z)a(O(CR 1 R 2)z )bY-(CR 3 R 4)2 - (CR 1 R 2)z O)c((CR 1 R 2)z OH)d.nR 5 OH(式I)其中:M是金属原子,优选钛,锆,铪或铁 选自P和N,但非常优选N; 每个R 1,R 2,R 3和R 4独立地选自H,烷基,芳基,取代的烷基或取代的芳基,R 5是氢,烷基,羟基官能化的烷基,聚氧烷基摩尔,R 10或R 7 COO,其中R 6和R 7可以各自 代表H,烷基,芳基或烷基 - 芳基; d和a分别为O或1,b和c各自为1或2,b + c = M的化合价,a + b + c + d = 4,每个z独立地为1,2,3或4; x表示Y原子之间的C原子数最少,为2或3,n为0至4的数。该金属有机化合物在水中形成稳定的水合物,保留路易斯酸催化性能。
