| | 1,1-DiMethyl-1,3-dihydrobenzo[c][1,2]oxasilole Usage And Synthesis |
| Physical properties | bp 45°C/2.0 mmHg. | | Uses | 2,1-Benzoxasilole, 1,3-dihydro-1,1-
dimethyl-?1 can reaction with Alkenyl and Aryl Nucleophiles. This reagent
reacts with various alkenyl- and arylmetallic reagents such as
Grignard reagents and organolithium reagents through cleavage/
formation of the Si–O/Si–C bonds to give alkenyl- or aryl[2-
(hydroxymethyl)phenyl]dimethylsilanes in good yields after
conventional aqueous workup (eq 2).![Reactions of 1,1-DiMethyl-1,3-dihydrobenzo[c][1,2]oxasilole](https://www.chemicalbook.com/NewsImg/2021-08-31/20210831100008881457990831.jpg "Reactions of 1,1-DiMethyl-1,3-dihydrobenzo[c][1,2]oxasilole") | | Preparation | by the halogen¨Clithium exchange reaction
of 2-(2-tetrahydro-2H-pyranoxymethyl)bromobenzene followed
by treatment with chlorodimethylsilane and subsequently
with a catalytic amount of p-toluenesulfonic acid in MeOH
(eq 1). The reagent is isolated by distillation under reduced
pressure. Large quantities can be prepared and stored in a
refrigerator.
