Novel silacyclobutanes useful as silylating agents and a process for their preparation are provided. The process comprises reacting a halogen substituted silacyclobutane with a silylating reagent to exchange the halogen substituents with groups on the silylating reagent. The novel compounds are of the formula ##STR1## wherein R' is a monovalent substituted or unsubstituted hydrocarbon radical or Y group; R" and R'" are independently hydrogen, monovalent substituted or unsubstituted hydrocarbon radical; and Y is selected from: ##STR2## and the disubstituted silacyclobutane wherein both Y and R' are ##STR3##
提供一种作为硅烷化剂有用的新型硅环丁烷化合物及其制备方法。该方法包括将卤素取代的硅环丁烷与硅烷化试剂反应,以交换卤素取代基与硅烷化试剂上的基团。这些新型化合物的化学式为##STR1##其中R'是一价取代或未取代的碳氢基团或Y基团;R"和R'"分别是氢、一价取代或未取代的碳氢基团;Y选自:##STR2##以及二取代硅环丁烷,其中Y和R'均为##STR3##
