Monoorganotin Precursors For Hybrid Materials

Universite de Bordeaux, Institut des Sciences Moleculaires, Groupe Materiaux, Talence, France 3.7.1 Introduction 

The behavior of alcohols 33 and 35 is different, as their chemical shifts in solution are moved upfleld with respect to the unfunctional analogs, more than for the corresponding esters, and are insensitive 

Experiments were also conducted to see whether that the alkynyl groups are perfect substitutes for alkoxyl groups towards hydrolysis. Indeed, when 4 is hydrolyzed, it leads to the same butyltin oxide-hydroxide cluster with 12 tin atoms as when butyltin triisopropoxide is used. Moreover, with the more bulky triisopropylphenyl group linked to the tin, two unusual oxide-hydroxide clusters, one with 10 tin atoms and the other with six, are produced, depending on the experimental conditions.
