## Abstract

A process for the production of organic substances, including the steps of providing at least a two-phase system, in which selected reactants are reacted in the presence of a phase transfer catalyst, where one of the phases is an organic solvent with a log P value, at 20° C., of more than 2.6, is provided.

## Claims

### Claim 1

A process for the production of organic substances, comprising the steps of:
providing at least a two-phase system, in which selected reactants are reacted in the presence of a phase transfer catalyst, wherein one of the phases is an organic solvent with a log P value, at 20° C., of more than 2.6.

### Claim 2 (depends on 1)

The process according to claim 1, wherein the two-phase system comprises a water phase, and an organic solvent with a log P value of more than 2.62.

### Claim 3 (depends on 2)
