Table 2 Time course of the yield* of products during longifolene autoxidation at 120 °C

From: Natural autoxidation of longifolene and anti-termite activities of the products

Time (h) Products** (%) Unreacted material** (%)
LC LL LAc isoLAc LHK L
1 0.50 0.58 <99
2 0.93 0.53 <99
4 2.4 0.86 87
8 7.5 1.7 1.1 0.79 71
12 17 3.4 2.3 1.1 1.6 62
24 23 4.3 3.0 1.3 2.2 22
  1. * Each yield was calculated by dividing the molar amount of product or unreacted longifolene by the molar amount of longifolene before reaction
  2. ** L, longifolene; LC, longicamphenylone; LL, norlongilactone; LAc, longifolic acid; isoLAc, isolongifolic acid; LHK, longifolene–hydroxy ketone
