2-Phenylselanyl-1,3-dienes 3-8 were prepared by a Wittig or Wittig-Horner-Emmons procedure starting from α-phenylselanyl α,β-unsaturated aldehydes. Ratio and configuration of each diene isomers were determined by 77Se and 1H NMR. The
Carbonyl propargylation and allenylation with 2-propynyl mesylates, tin(IV) iodide, and tetrabutylammonium iodide controlled by either a steric effect or coordination effect

A combination of tin(IV) iodide and tetrabutylammonium iodide can be used for propargylation or allenylation of aldehydes with 2-propynyl mesylates in dichloromethane. 1-Methyl-2-propynyl mesylate or 2-butynyl mesylate results in propargylation or allenyl
Carbonyl allenylations and propargylations by 3-chloro-1-propyne or 2-propynyl mesylates with tin(IV) chloride and tetrabutylammonium iodide

By the use of tin(IV) chloride and tetrabutylammonium iodide in dichloromethane, 3-chloro-1-propyne or 2-propynyl mesylate can be applied to allenylation and propargylation of aldehydes (carbonyl allenylation and propargylation) to produce a mixture of 1-
