An implant trocar for treating animals comprises a reciprocatory plunger within a pellet-containing barrel. The plunger is controlled by an operating shaft extending through a guiding slot in the wall of the barrel. A curved finger grip extends from the barrel opposite the operating shaft and enables the rounded heel of the barrel to be located against the palm of the hand of the user.

Covers a composition comprising the combination of 1-dopa, 2-imino-5-phenyl-4-oxazolidinone or salt thereof and a third agent comprising an aluminum or alkaline earth metal salt or base and use of said composition in treating Parkinson's disease. 7 Claims, No Drawings

An inhaler for self-administration of a volatile drug for analgesic purposes and comprising a tubular body with a mouthpiece at one end for insertion into a patient's mouth, an absorbent material within the tubular body for holding the liquid agent and a cap on the end of the tubular body opposite the mouthpiece, the cap having openings therein arranged to provide evenly distributed charging of liquid drug.

A process for preparing a dimethylorganoborane represented by the formula R*BMe.sub.2 wherein R* is a chiral organyl group attached to the boron, B is boron and Me is methyl comprising treating a chiral boronic ester R*B(OR').sub.2 with a methyl magnesium salt or trimethylaluminum wherein R* is the same chiral organyl group and R' is alkyl.

Novel mono- and diisopinocampheylhaloboranes, represented by the formulae IpcBX.sub.2 and Ipc.sub.2 BX wherein Ipc is isopinocampheyl and X is halo, as well as processes for making and using same.

Improved processes for liberating boronic, RB(OR').sub.2, and borinic, RR'BOR', esters from their "ate" complexes, free of alcohol are provided. Pyrolysis of lithium organylborates LiRB(OR').sub.3 and LiRR'BOR', wherein R is an organyl group and R' is straight or branched-chain lower alkyl, directly yields the relatively volatile boronic and borinic esters in high purity, leaving behind a residue of lithium alkoxide. Treatment of the lithium organylborates with an appropriate acid halide cleanly...

A process for synthesizing an optically pure ketone comprising the steps of: treating an appropriate optically pure boronic ester with an organolithium compound at -78.degree. C. to obtain the "ate" complex, separating the optically pure borinic ester from the complex and converting said borinic ester into an optically pure ketone represented by the formulae: wherein R* is a chiral organyl moeity and R.sup.1 is an achiral organyl moeity.

A novel process for producing hindered and unhindered primary amines represented by the formula RNH.sub.2 and R*NH.sub.2 in high yields from novel intermediates RBMe.sub.2 or R*BMe.sub.2 wherein R is an organo group, R* is a chiral organo group, attached to boron, B is boron and Me is methyl.
