, p. 5139 - 5142 (1993)
The Significance of electrostatic effects on the origin of π-facial stereoselectivity in nucleophilic additions to β,γ-unsaturated carbonyl systems was shown through theoretical studies (ab initio MO calculations of transition structures for NaH + HCOCHs
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
Masuyama, Yoshiro,Watabe, Akiko,Kurusu, Yasuhiko
, p. 1713 - 1715 (2007/10/03)
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-
