Computational details and NMR spectra for compounds 3, 4, 5 and 6
DFT calculations were carried out using the Gaussian G03 computational package [1]. The
B3LYP density functionals [2,3] were used along with the 6-311G(d,p) basis set [4,5]. After
the geometry optimisation of each molecule, a frequency analysis was carried out. The
resulting calculated zero-point energy was added to the electronic energy and this is the
energy value quoted below.
