Silane, 1,1'-(1-propyne-1,3-diyl)bis[1,1,1-tris(1-methylethyl)- C화학적 특성, 용도, 생산

물리적 성질

bp 130–135°C/0.08 mmHg; d 0.846 g cm?3.

용도

1,3-Bis(triisopropylsilyl)propyne is a precursor of a stereoselective bulky C3 nucleophile, functionalized Peterson reagent.
The main use of the title reagent is as a precursor of the lithium derivative. 1,3-Bis(triisopropylsilyl)propyne is cleanly lithiated by treatment with equiv of n-butyllithium in THF at ?20°C (15 min) to what is probably an equilibrium mixture of propargylic and allenic species (1) and (2) (eq 1).The bulky triisopropylsilyl (TIPS) group serves as a controlling group in the addition of (1/2) to electrophiles.	Silane, 1,1'-(1-propyne-1,3-diyl)bis[1,1,1-tris(1-methylethyl)-

제조 방법

1,3-bis(TIPS)propyne is prepared in quantitative yield by silylation of 3-lithio-1-triisopropylsilyl-1- propyne with triisopropylsilyl trifluoromethanesulfonate.
