N-CAPROIC ACID ISOPROPYL ESTER synthesis

10synthesis methods
By esterification of hexanoic acid with isopropyl alcohol in benzene solution in the presence of trace amounts of concentrated H2SO4 and subsequent azeotropic distillation
-

Yield:-

Reaction Conditions:

Stage #1:penta-1,3-diene;isopropyl alcohol with tris-(dibenzylideneacetone)dipalladium(0);methanesulfonic acid;1,2-bis[di(t-butyl)phosphinomethyl]benzene in methanol for 0.25 h;Sonication;Schlenk technique;
Stage #2:carbon monoxide with hydrogen in methanol under 22502.3 Torr;

Steps:

4 Standard experimental procedure
General procedure: All screening experiments were performed in a 20 ml home-made multiplex reactor [48]. In an typical experiment 87.5 mg(0.10 mmol) Pd2(dba)3 and 301.8 mg (0.75 mmol) 1,2-dtbpmb,869.1 mg (12.75 mmol) piperylene, 98.0 mg (1.02 mmol) methane-sulfonic acid and 10 ml methanol were placed in a Schlenck-vessel.The mixture was placed in an ultrasonic bath for 15 min. The mix-ture was transferred to an evacuated and ame-dried reactor andsubsequently charged with 30 bar synthesis gas. The mixture wasplaced in an oil bath at reaction temperature e.g. 110 C for vehours. After cooling to room temperature the mixture was depres-surised and analysed by GC-FID.
