ABSTRACT:
Triarylborane derivatives corresponding to the formula (1) ##STR1## in which R either represents a group --CR.sub.1 R.sub.2 R.sub.3 where R.sub.1, R.sub.2 and R.sub.3 are each, independently of one another, a (C.sub.1 -C.sub.2)alkyl or aryl group, or represents a group --CH.sub.2 OR.sub.4 where R.sub.4 is a (C.sub.1 -C.sub.2)alkyl or benzyl group, or represents a group --Si(R.sub.5).sub.3 where R.sub.5 is a (C.sub.1 -C.sub.2)alkyl or aryl group, R being in the 1 or 2 position of the tetrazole ring, their preparation and their use as synthesis intermediates.
