Titanasilsesquioxane alkoxides

A series of titanasilsesquioxane alkoxides, including [R7Si70i2Ti0zPr] (107, R = C-C5H9 108, c-CfiHn = 1,2) and [Cy7Si70i2Ti(p-0Me)(Me0H)]2 (109) were published by Crocker and co-workers. " Treatment of Cy7Si70i2Ti(0Pr) (108) with methanol affords the six-coordinate titanasilsesquioxane dimer [Cy7Si70i2 Ti(p-OMe)(MeOH)]2 (109), which was structurally characterized. The monomer/ dimer equilibrium of 108 and the formation of 109 are depicted in Scheme 34. " ...
