Zinc dipropyl

Zinc Dipropyl. Zn(C3H7)2, C6H14Zn mw 151.5 5 mobile pyrophoric liq, stable in a sealed tube under C02 bp 160° d 1.1034g/cc at 20/4° RI 1.4845 at 18.6°. Sol in org solvents decomps explosively on contact with w. Prepn is by reacting n-propyl iodide with Zn. The compd has a heat of combstn of 11133 5.6 kcal/mole(Refs3,p 181 6, p 491M-444)... 

A variation of the method was described in 1884 by Pape, who used a mixture of silicon tetrachloride and propyl iodide with metallic zinc instead of preparing the zinc dipropyl separately. Another variation, exploited by Friedel and Ladenburg, eliminated the sealed tube by introducing metallic sodium along with the zinc alkyl and silicate ester ... 

Prop d iodide, 140 grams, and 5 grams of sodium zinc alloy are heated with 280 to 350 grams of zinc turnings for four to five days on the water-bath. Distillation of the product gives a 43 to 50 per cent, yield of zinc dipropyl. ... 

Zinc dipropyl is a colourless, heavy liquid of very unpleasant smell, and its boiling-point differs according to the various investigators as follows 146° C. (Gladstone and Tribe) 148° C. (Schtscherbakoff) 150° C. (Pape) 158° to 160° C. (Cahours). It undergoes the following reactions —... 

Chiorodi methyl ether with zinc dipropyl yields methyl-n-butjd ether. ... 

Zinc di-isobutyl is a liquid, B.pt. 165° to IGT Tl., less readily oxidised than zinc dipropyl. It reacts vigorously with trihalides of phosphorus and arsenic, yielding corresponding phosphines and arsines. With acetaldehyde it forms principally ethyl alcohol, but also a little isobutyl alcohol, and with isovaleryl chloride it gives di-isobutyl ketone. ... 

Zinc decomposes mercury diproj yl at 100° to 120° C. with the formation of zinc dipropyi aluminium at 130° C. yields aluminium tripropyl, and beryllium gives beryllium dipropyl.
