Bis‐Dichlorosilyl Functionalized C4‐Cumulene With Unique Bonding Scenario
Chemistry – A European Journal, EarlyView.Herein, we report a silylene‐functionalized C4‐cumulene (2) and investigate its bonding scenario employing computational methods such as NBO analysis, AIM, and energy decomposition analysis‐natural orbital for chemical valence (EDA‐NOCV). The EDA‐NOCV analysis showed that compound 2 prefers to possess electron‐sharing covalent sigma and dative covalent
