The hydroboration of protected allylalcohols by two different groups gives no linear structures of siloxypropylboranyls as predicted but gives the C–B–O five membered ring 1,2-H-oxaborolanes with good yield. A mechanism is also proposed to explai

The protection of the hydroxy group of p-cresol 1 by o-silylation gives derivatives 2 and 3 , the methyl group of which can be brominated by NBS. The phase transfer catalysis applied to 4 and 5 is a good way which permits the mild introduction of the
