Synthetic transformations mediated by the combination of titanium(IV) alkoxides and Grignard reagents: selectivity issues and recent applications. Part 2: Reactions of alkenes, allenes and alkynes

摘要

In summary, regioselectivity results from a complex combination of additive or conflicting factors, the analysis of which can help understanding and predicting results. The directing effects of some common groups are summarised in Table 1. Nonetheless, the regioselectivity is detailed in each of the following relevant sections,given the variations caused by the nature of the reagents used.
