eng	LITHIUM BIS(AMIDO)SILYL AMIDES SERVING AS CONTAINERS FOR ORGANOLITHIUM REAGENTS	Bulky bis(amido)silyls are known as suitable protoligands for stabilization of enylenes since 1975 in which Veith prepared the first such a stanylene. His work was further extended to germylene and silylen species.1 In our group series of new sterically demanding bis(amido)silyls was prepared. These protoligands were further used in the preparation of stanylenes by their deprotonation with n-BuLi and subsequent reaction with SnCl2. During the search for possible causes of low reaction yields, it was found that the addition of deprotonating agent leads to double deprotonation and subsequently formation of an adduct with a molecule of deprotonating agent such as n-BuLi or MeLi. Considering the fact that this behaviour has not yet been described in the literature, the investigation of this phenomenon and the targeted synthesis of these compounds and their characterization is crucial for our further research
