Abstract Ethylene glycol isonitriles C≡ N (CH 2 CH 2 O) n CH 3 (5a, n= 1; 5b, n= 3; 5c, n= 4) with different chain lengths were prepared by using straightforward synthesis methodologies including the Gabriel synthesis and an Appel-type reaction protocol. Upon treatment with [AuCl (SMe) 2], compounds 5a–c gave the corresponding isocyanide gold (I) chlorides [AuCl {C≡ N (CH 2 CH 2 O) n CH 3}](7a, n= 1; 7b, n= 3; 7c, n= 4). Single-crystal X-ray diffraction ...
