Patent ID: 6861384

Claim:
A process for preparing compounds of the formula (I): (C 6 R 1 5 ) 3 MR 2 (1) where R 1 are identical or different and are each a hydrogen atom, a halogen atom, C 1 -C 20 -alkyl, C 6 -C 14 -aryl, C 6 -C 14 -aryl, C 1 -C 10 -alkoxy, C 2 -C 10 -alkenyl, C 7 -C 20 -arylalkyl, C 7 -C 20 -alkylaryl, C 6 -C 10 -aryloxy, C 1 -C 10 -haloalkyl, C 6 -C 10 -haloaryl, C 2 C 10 -alkynyl or C 3 -C 20 -alkylsilyl; M is an element of main group III of the Periodic Table of the Elements; and R 2 is a substituted or unsubstituted heterocycle; wherein the compounds of formula (I) are salt-like; the process comprising firstly reacting heterocycles R 2 containing elements of main group I or II of the Periodic Table of the Elements with compounds of the formula (C 6 C 1 5 ) 3 M in a solvent to form compounds of the formula [(C 6 R 1 5 ) 3 MR 2 ] which are subsequently protonated by reaction with a proton donor.
