On pentaorganylstiborane. III. Regio- and diastereoselective additions of acetylenic and allenic organoantimony compounds to aldehydes
Zhang, Li-Jun,Mo, Xue-Sheng,Huang, Yao-Zeng
, p. 77 - 86 (2007/10/02)
The reaction of propargyl bromide (4a) with tributylstibine gave allenyltributylstibonium bromide (5), and its corresponding pentaorganylstiborane reacted with aldehyde to give homopropargylic alcohol (10a) exclusively in good yield.However, the reaction
Regioselective reactions of trimethylsilylpropargylic and trimethylsilylallylic organoantimony compounds with aldehydes

The reactions of trimethylsilylallylic organoantimony compound with aldehydes show very high selectivity favoring α-adducts; and the reactions of trimethylsilylpropargylic organoantimony compounds with aldehydes also exhibit very high acetylenic selectivity (α-adducts) in the presence of LiBr.

The propargyltitanium reagents derived from 1-alkylpropyne condensed with aldehydes to give α-allenyl alcohol regioselectively, while the allenyltitanium reagents generated from 1-alkyl-1-butyne derivatives gave threo-β-acetylenic alcohols with high regio- and stereoselectivities.The course of the reaction was determined by the substitution pattern of starting alkynes.The similar reactions of metallated 1,3-bis(trialkylsilyl)propyne or (trialkylsilyl)acetonitrile with aldehydes were also investigated.

SILANES IN ORGANIC SYNTHESIS. 11. REGIOCONTROLLED SYNTHESIS OF α-HYDROXYMETHYLATED (TRIMETHYLSILYL)ALLENES
Daniels, Rhys G.,Paquette, Leo A.
, p. 1579 - 1582 (2007/10/02)
The organometallic produced by reaction of trimethylsilylpropargyl bromide with aluminium amalgam in anhydrous tetrahydrofuran condenses readily with aldehydes and ketones to give allenic alcohols resulting from coupling α to the trimethylsilyl substituen
