DIISOPROPYLDICHLOROSILANE Chemical Properties,Uses,Production
Physical properties
bp 50–55°C/5 mmHg.
Uses
Dichlorodiisopropylsilane can be used in nucleoside 3',5'-hydroxy protection; component in Peterson alkenation reaction.
The use of silicon groups as protection for hydroxy groups has been widely exploited.3 One potentially useful way to protect a nucleoside is by using a protecting group which spans the 3- and 5-hydroxy groups. One of the useful groups which can be used as a bifunctional protecting group in nucleosides is the diisopropylsilyl group. Reaction of the nucleoside with dichlorodiisopropylsilane and imidazole in DMF gives the protected nucleoside (eq 1).This method has not been widely used; the more common 3',5'-hydroxy-bridging protecting group is a tetraisopropyldisiloxy group.
Preparation
conveniently prepared by the reaction of diisopropylsilane in carbon tetrachloride with palladium(II) chloride at 140°C for 8 h in a steel bomb.Washing the residue with ether and removing the ether by rotary evaporation yields the product which is purified by distillation to yield a clear colorless oil.
storage
Special care should be used when handling since Dichlorodiisopropylsilane is corrosive.
