Reactions of 1‐lithio · DME‐2,4‐bis(dialkylamino)‐l,3,2,4‐diphosphadiboretanes ( 1a, 1b ) with SiCl 4 followed by dehydrohalogenation with t BuLi produce spirocyclic compounds [(R 2 NB) 2 P 2 ] 2 Si ( 2a, 2b ). The compounds have been characterized by spectroscopic methods and X‐ray crystallography. The assembly process has also been followed and one intermediate species [( i Pr 2 NB) 2 P 2 ][( i Pr 2 NB)P(H)( i Pr 2 NB)P]SiCl ( 3 ) has been isolated and fully characterized.
