Characterization and thermal activation of adducts of Group 4 tetrahalides with 1,2-dialkoxyalkanes

Coordination compounds of general formula MX4[κ2-O(R)CH2CH(R′)OR′′], 2a-i, have been prepared and characterized spectroscopically. The thermal stability has been studied: fragmentation of the organic ligand is observed in correspondence of low metal−halide bond energy.
