What is Ambiphilicity of Dichlorosilylene in a Single Molecule about?

## Dedicated to Professor Josef Michl on the occasion of his 70 th birthday In general, silylenes (R 2 Si, in which R = H, halogen, alkyl, or aryl) are divalent neutral silicon species with the lone pair of electrons as the HOMO and an empty p orbital as the LUMO in the singlet ground ( 1 A) state. Therefore, silylenes can in principle behave as Lewis acids as well as Lewis bases, depending on the substituents. Silylenes are known to have an ambiphilic [1] nature (A and B in Scheme 1). The availability of simultaneously electrophilic and nucleophilic center in the same molecule such as a silylene (A), has been intriguing both to theoretical [1] and experimental [2] scientists during the last few decades. A fair number of examples of insertion or addition reactions of stable silylenes have been reported. [3] The reactions in which silylenes function as Lewis bases are limited. [4,5] The base-catalyzed generation of silylenes as reaction intermediates and their trapping products are known. [6] Many transient silylene complexes with Lewis bases were postulat-ed in low-temperature matrices, [7] but the first stable silylene Lewis base complex was isolated by Okazaki et al. in 1997 by t
