Synthesis and Molecular Structure Studies of [Me2AlN(i-Pr)CH2Ph]2 and the Related Orthometalated Dimers [RAlN(i-Pr)-μ-(CH2C6H4)]2, where R = Me, n-Pr, n-Bu, i-Bu
摘要:
[Me2AlN(i-Pr)CH2Ph](2) (1) and the related dimer series [RAlN(i-Pr)-mu-(CH2C6H4)](2) R =Me (2), n-Pr (3), n-Bu (4), and i-Bu (5), were synthesized by thermolysis of 1:1 mixtures of R3Al and HN(i-Pr)CH2Ph. The reaction times and temperatures required and the molecular structure and NMR data for 1-5 are compared with reported data for [Me2AlN(CH2Ph)(2)](2) and the series [RAlN(CH2Ph)-mu-(CH2C6H4)](2) and [RAlN(t-Bu)-mu-(CH2C6H4)](2).
