Experimental Conditions: a. Microwave heating, DMF, Lewis acid. b. 6 mol% Pd(0) EnCat™ 30NP, EtOAc, HCOOH, NEt3, 24°C, 24 hours or 6 mol% Pd(0) EnCat™ 30NP, EtOAc, HCOOH, NEt3, microwave heating, 120°C, 2 hours

Debenzylation

Pd(0) EnCat™ 30NP can be an efficient catalyst for the selective reductive hydrogenation of aryl benzyl ethers, benzyl esters, and benzyl amines leaving other sensitive groups intact.
Alkyl benzyl ethers are not reduced under atmospheric pressure of hydrogen with Pd(0) EnCat™ 30NP

Experimental Procedure:
The substrate was dissolved in EtOH, 10 mol% of the catalyst (water wet) was added and the mixture degassed twice under vacuum refilling each time with hydrogen. The reaction mixture was left at room temperature overnight connected to hydrogen. The catalyst was then filtered off and washed with EtOH. The filtrate was concentrated to give a crude product which was submitted for 1H-NMR analysis to determine the conversion
