Particular success has been achieved in the synthesis of new products and in processes
since the twelve principles of “green chemistry” were formulated in the 1990s. These …

Abstract A range of phosphorus-stabilized carbon nucleophiles have been employed for
alkene synthesis with high chemo-, regio-, and stereoselectivity. The Wittig, Horner …

Water is demonstrated to be an effective medium for the Wittig reaction over a wide range of
stabilized ylides and aldehydes. Despite sometimes poor solubility of the reactants, good …

Multibranched π-conjugated materials and hyperbranched polymers have received
considerable interest in both academic research and industrial applications because of their …

30 Seconds to success!–The Wittig reaction, a fundamental and extensively utilized reaction
in organic chemistry, enables the efficient conversion of carbonyl compounds to olefins …

Developments in the Wittig and Horner-Wadsworth-Emmons (HWE)-olefination of aldehydes
and ketones with stabilised phosphoranes or phosphonates provide opportunities for …

A general and practical synthesis of (E)‐α, β‐unsaturated esters and ketones was achieved
by the reaction of carbonyl compounds with ethyl‐4, 4, 4‐trifluoroacetoacetate and trifluoro …

The C–C bond formation reactions are important in organic synthesis. Heck reaction is
known to arylate the terminal carbon of olefins; however, direct alkylation of the terminal …
