Organic synthesis in water mediated by silyl radicals

This account is focused on highlighting the recent advances on synthetically-useful organic reactions employing siliconcentered radicals in water, and presenting new reactions in water, mediated by silyl radicals. In doing so, several types of organic radical transformations will be discussed, such...
