Silicon compounds oxygen insertion

Chemical reactions change only forms of existence of basis components in compliance with conditions of mass conservation law. Proportions, which equate moles of the components before and after reactions, are called stoichiometric coefficients or simply reaction coefficients. In reaction equations these coefficients are inserted before formulae of the compounds themselves. For instance, the silicon, when solved in water, forms orthosilicic acid, which with increase in pH loses oxygen. For this reason the entire reaction of dissolving SiO may be expressed by the equation... 

A series of novel silicon-, germanium-, or tin-functionalized cumulenes (218) has been prepared by insertion of alkadienylidenecarbenes (217) into the appropriate metal hydrides. The cumulenes are isolable but moderately oxygen-sensitive compounds that rearrange or polymerize on standing at room temperature. An improved synthesis of 1,2,3-butatrienyl ethers has been developed. ...
