Typical epoxides such as cyclohexene oxide and cis- and trans-but-2-ene oxide are converted to titanium enolates by heating at 80 °C with the title compound.

Synthesis graphs are redefined as digraphs(directed graphs) which leads to the consideration of the ‘vulnerability’ of synthetic plans and its relationship to the risk of failure upon execution of the plan.

Specifically 13C-labelled benzoins have been prepared by the O-(trimethylsilyl)cyanohydrin method in a completely regiospecific manner and shown to be extremely sensitive to scrambling, thus establishing this acyl-anion equivalent as the best one for labile products.

The concept of the bond graph is introduced for the extension of ‘branching’ and ‘topological’ indices from saturated to unsaturated hydrocarbons as the key step in the construction of a general index of complexity for molecular skeletons.

New Heterocuprates based upon phosphido-and amido-ligands have exceptional thermal stability, which can be traced to steric, electronic, and co-ordination effects.

Lithium isopropyl dithioisobutyrate is alkylated on the S atom by 4-bromocylopent-2-enone but on the C atom by cyclopent-2-enone and 4-acetoxycyclopent-2-enone via conjugate addition; the stereochemistry of the 3,4-disubstituted cyclopenanone from the latter reaction is established by the determination of the long-range coupling constants, 4JHH.
