catalyst: dibenzo-18-crown-6 in N,N-dimethyl-formamide 160°C; excess KI;; analyzed by GLC;;

sodium in Petroleum ether (Ar); vigorous stirred suspn. of Na was maintained at 115°C for 0.5 h, one drop of SnCl4 was added and ClC4H9 was added dropwise within 3 h at 30-40°C, after 1 h stirring SnCl4 (4:1 mol) was dropped into mixt. (same temp.) within 75 min; after stirring for a further h at 30-40°C mixt. was filtered off and residue treated with tBuOH, solvents were distd. off from filtrate; identification by GC after methylation;

tert-butyl methyl ether; tin(IV) chloride T=50°C; 0.75 h; Product distribution / selectivity;

mercury dichloride in ethanol reflux;

(η5-C5H5)2Zr(H)Cl in hexane; benzene mixt. of Cp2ZrHCl and 1-octene in benzene was stirred for ca. 2 h at room temp. under nitrogen, hexane soln. of (n-octyl)SnCl3 was added, mixt. was refluxed in the presence of added solvents such as n-Bu2O and DMF;
