2,2-Dichloro-1,3-bis(trimethylsilyl)-1,3,2-diazastanna-[3]ferrocenophane (3) reacts with lithium alkynides LiC CR 1 to give the corresponding di(alkyn-1-yl)tin derivatives 4a (R 1 = t Bu) and 4b (R 1 =SiMe 3 ). 1,1-Organoboration of 4 with triethylborane affords the spirotin compounds 5 which contain both a ferrocenophane and a stannacyclopentadiene ring. The crystal structure of 5b was determined by X-ray analysis. The compounds 4 and 5 were characterised in solution by multinuclear magnetic resonance ( 1 H-, 1 1 B-, 1 3 C-, 1 5 N-, 2 9 Si-, 1 1 9 Sn-NMR), using pulsed field gradients in HMBC experiments for the 1 H detected 1 5 N- and 1 1 9 Sn-NMR signals. The compound 5b was also studied by solid-state 1 3 C, 2 9 Si and 1 1 9 Sn MAS NMR in order to correlate liquid and solid-state NMR data with the structural evidence.
