It's hip to be square : The reaction of amidinato chlorosilylene (PhC(N t Bu) 2 SiCl) with adamantyl phosphaalkyne and white phosphorus affords the formation of Si‐C‐Si‐P and Si‐P‐Si‐P (see picture) four‐membered rings. Both compounds were characterized by single‐crystal X‐ray studies and by solution and solid‐state NMR spectroscopy. DFT calculations elucidated the bonding situation.
