Substituted -Butyrolactones From Carboxylic Acids and Olefins 7- -Octyl -y-Butyrolactone

Submitted by E I Heiba R M Dessau A L Williams and P G Rodewald Checked by Gerald E Lepone and Orville L Chapman 

The checkers used manganous acetate tetrahydrate obtained from Fisher Scientific Company. This compound is more readily available than manganous acetate dihydrate used by the submitters and obtained from the Harshaw Chemical Company. 

If the dihydrate is used, only 76.7 g (0.751 mol) of acetic anhydride is required. 

1-Decene was used as obtained from the Humphrey Chemical Company. 

The checkers found the yield based upon olefin consumed to be 85%. This discrepancy could be accounted for by losses due to the high volatility of 1-decene at reduced pressure.
