To ice cold tetra-iso-propyltitanate (titanium (IV) isopropoxide) (9.55 g; 0.033M) in a distillation flask, acrylic acid (4.8 g; 0.066M) was added. The mixture was subjected to vacuum distillation ca. 1 mm Hg (133 Pa) at 37° C. on a rotary evaporator to remove iso-propanol ca. 4.4 g. The product is the distillation flask was 10.1 g (97% of theory) of a yellow liquid. The results of NMR spectral analysis are summarised in Table S3 below. It was not possible to obtain useful IR spectra because the product hydrolysed rapidly. These results are consistent with the product being the title compound as such but we think it probable that the product is in fact a statistical mixture of the possible acrylate products and possibly unreacted starting material, the product having the `average` composition corresponding to the title compound.
